Are Mazda MX-5s Cheap to Insure? Costs Explained
If you are thinking about buying an MX-5, you may be asking: are Mazda MX-5s cheap to insure? Considering that the Mazda MX-5 is a two-seat, rear-wheel-drive sports car, the answer may be pleasantly surprising.
In many circumstances, Mazda MX-5 insurance can be relatively affordable compared with other sports cars. Recent UK insurance data supports this. In April 2026, Go.Compare reported an average annual premium of £232 for the Mazda MX-5 within its analysis of the UK's cheapest cars to insure. The overall UK average quoted in the same study was £403.
That does not mean every MX-5 owner will pay £232. Your actual insurance premium depends on the exact Mazda model, your age, postcode, driving experience, driving history, mileage and numerous other factors.
At MX5 City, we specialise in all things MX5, from cars and parts to servicing, repairs and upgrades. Insurance is another ownership cost worth investigating before choosing your next Mazda MX5.
What Insurance Group Is a Mazda MX-5?
Mazda MX-5 insurance groups vary considerably between models.
Current data published by Finder places different Mazda MX-5 models between insurance groups 21 and 34. For example, an older 1.8i SE can fall into group 21, while some 2.0-litre models, special editions and higher-performance versions can sit above group 30.
This is important because insurance groups run from 1 to 50. However, the group number is only one factor used by insurance companies when calculating rates.
A Mazda MX-5 in insurance group 21 will not automatically generate cheap car insurance for every driver. Equally, a model in group 30 or above will not necessarily be prohibitively expensive.
Why Can Mazda MX-5 Insurance Be Relatively Affordable?
The Mazda MX-5 has always followed a slightly different formula from many sports cars.
Rather than relying on enormous engines and extreme power outputs, the Mazda MX-5 is built around light weight, balance and driver involvement.
This can work in its favour.
Even modern versions provide relatively modest power compared with many performance cars. Replacement values can also be considerably lower than expensive premium sports cars.
There is also a huge population of MX-5s in the UK. Parts availability is generally good, particularly when dealing with an MX-5 specialist such as MX5 City.
The result is that an MX-5 can sometimes produce surprisingly affordable premiums.
Why Might an MX-5 Be Expensive to Insure?
There is another side to the equation.
The Mazda MX-5 is still a sports car. It is rear-wheel drive, many models are convertibles, and MX-5s are popular with enthusiasts.
Higher-powered versions may also fall into higher insurance groups.
Modified vehicles can present another issue. An MX-5 fitted with non-standard suspension, wheels, engine upgrades, exhaust components or body modifications must normally have those changes declared to the insurer.
This does not necessarily mean modified Mazda insurance will be expensive. Specialist insurance providers may actually be better equipped to understand modified and classic MX-5s than mainstream insurers.
The important thing is to provide accurate policy details and declare relevant modifications.
How Much Does Mazda MX-5 Insurance Cost?
There is no meaningful single Average Cost that applies to everyone.
One 2026 analysis by Finder estimated comprehensive Mazda MX-5 insurance at an average of £1,090.79 per year. However, its calculation deliberately averaged hypothetical drivers aged 20, 30, 40 and 50 across cheap, medium and expensive postcodes.
Contrast that with Go.Compare's 2026 sales data, which found an average premium of £232 for the Mazda MX-5 among policies in its study.
The huge difference demonstrates why you should be careful with online claims about average premiums and average rates.
The question is not really "What does an MX-5 cost to insure?"
It is "What will my particular MX-5 cost me to insure?"
What Affects Mazda MX-5 Insurance Costs?
Car insurance costs are calculated using a combination of information about the vehicle and the people driving it.
Insurance providers can consider factors including:
- Your age
- Postcode
- Occupation
- Driving experience
- Driving history
- Claims and convictions
- No-claims bonus
- Annual mileage
- Where the vehicle is kept overnight
- Exact Mazda model
- Engine size
- Vehicle age and value
- Modifications
- Car's security
- Safety features
- Type of insurance policy
- Voluntary excess
Current Go.Compare guidance confirms that factors including age, location, mileage, occupation, vehicle model and modifications can influence the quotes offered by insurers.
This is why two people living a few miles apart can receive completely different rates for exactly the same Mazda MX-5.
Are MX-5s Cheap to Insure for Young Drivers?
This is where things become more complicated.
Young drivers generally pay significantly more for insurance because insurers' claims data associates younger and less experienced motorists with greater risk.
An MX-5 can therefore be affordable for an experienced driver with a substantial no-claims bonus, yet expensive for a newly qualified driver.
Finder's modelling illustrates the difference. Its example quotes for a 2005 to 2015 1.8i SE ranged from approximately £1,072 for a 20-year-old to £528 for a 50-year-old, although those figures are illustrative rather than quotations that individual drivers should expect to receive.
For a young driver comparing an MX-5 with something such as a Fiat Panda, the conventional small hatchback may produce a cheaper quote. In Go.Compare's 2026 figures for drivers under 25, the Fiat Panda was among the ten cheapest models, with an average premium of £578.
Building a clean driving history and accumulating a no-claims bonus can make a substantial difference over time.
Do Older MX-5s Cost Less to Insure?
Not necessarily, but they can.
An older Mazda MX-5 Miata, UK MX-5 or Japanese-market Eunos Roadster may have a relatively low vehicle value. Some older vehicles may also qualify for specialist classic-car policies, depending on the vehicle and how it is used.
However, age alone does not guarantee cheap car insurance.
Insurers consider claims risk, replacement parts, repair costs, modifications, security and the driver's profile.
Older Mazda cars can also have fewer modern safety features and security systems than a new car.
Always obtain quotes for the exact registration rather than assuming an NA, NB or NC will automatically be cheaper than a newer Mazda model.
Does the MX-5 RF Cost More to Insure?
It can.
Different MX-5 RF models occupy different insurance groups. Finder currently lists examples ranging from group 24 for a 1.5 Prime-Line to group 33 for the 2.0-litre 30th Anniversary RF.
Engine size, specification, performance, replacement value and equipment can all affect the eventual insurance premium.
The same principle applies to specifications such as Sport Nav and special editions.
Compare the exact model rather than assuming every Mazda MX5 will produce similar rates.
Is Comprehensive Coverage Worth Having on an Older MX-5?
Many owners assume third-party insurance must be cheaper because it provides less cover.
That assumption can be wrong.
Go.Compare's July 2026 figures showed median annual prices of around £404 for comprehensive insurance, £417 for third party, fire and theft, and £608 for third-party-only policies.
Those figures cover car insurance generally rather than MX-5s specifically, but they illustrate an important point: comprehensive coverage can sometimes cost less than more limited coverage.
When comparing an insurance policy, therefore, obtain prices for comprehensive coverage as well as more basic options.
Also compare what each policy actually provides. The cheapest quote is not automatically the best insurance policy.
Can Modifications Increase Mazda MX-5 Insurance?
They can, which is particularly relevant to MX-5 enthusiasts.
Many MX-5s have been modified during their lives. Changes may include:
- Alloy wheels
- Lowered or upgraded suspension
- Exhaust systems
- Roll bars
- Bodywork changes
- Engine modifications
- Brake upgrades
- Interior modifications
Always tell your insurer about modifications that need to be declared.
Some mainstream insurance companies may increase their rates, while specialist insurance providers may be more comfortable covering modified vehicles.
At MX5 City, we regularly deal with replacement parts, repairs and upgrades for different generations of Mazda MX-5. If you are considering modifying your car, it makes sense to investigate the insurance implications before carrying out the work.
How Can You Get Cheaper Mazda MX-5 Insurance?
If you want cheap car insurance for an MX-5, comparison is important.
Try obtaining quotations from several insurance providers rather than automatically renewing with your existing insurer.
You can also investigate whether a sensible increase in voluntary excess produces a cheaper quote. Lower annual mileage may help some drivers, while improved vehicle security and secure overnight parking can also affect rates.
Protecting and building your no-claims bonus can become particularly valuable over the longer term.
For older, unusual, imported or modified MX-5s, consider specialist insurers as well as mainstream insurance companies.
Most importantly, compare equivalent policy details. Check excesses, mileage limits, modifications, breakdown cover, legal assistance and any optional coverages before deciding which policy provides the right balance.
Frequently Asked Questions About Mazda MX-5 Insurance
Are Mazda MX-5s expensive to insure?
Not necessarily. Although the Mazda MX-5 is a sports car, UK data suggests it can be relatively inexpensive to insure for some drivers. Go.Compare's April 2026 analysis put the MX-5's average premium at £232, compared with a £403 overall UK average in that particular dataset. Your own premium could be considerably higher or lower.
What insurance group is a Mazda MX-5?
Mazda MX-5 insurance groups vary according to the model, engine, age and specification. Current Finder data places examples between groups 21 and 34. Always check the exact model because a 1.8-litre older MX-5, 2.0-litre Sport Nav and modern MX-5 RF can have different ratings.
Is an MX-5 cheap to insure for a 20-year-old?
It may be considerably more expensive for a 20-year-old than for an experienced driver. Young drivers usually face higher premiums because age and driving experience affect insurers' assessment of risk. Obtain personalised quotes before buying the car.
Can a no-claims bonus make an MX-5 cheaper to insure?
Yes. A no-claims bonus or no-claims discount can influence the price offered by insurance providers. Your driving history, claims record and driving experience will also be considered.
Is fully comprehensive MX-5 insurance more expensive?
Not always. Comprehensive coverage can sometimes be cheaper than third-party policies. UK-wide Go. Compare figures from July 2026 demonstrate that comprehensive insurance can cost less on average than third-party-only cover, so it is worth comparing all suitable levels of protection.
Is a Eunos Roadster more difficult to insure?
A Eunos Roadster is a Japanese-market version of the MX-5 and is therefore an imported vehicle in the UK. Some mainstream insurers may treat imports differently, so owners may benefit from comparing specialist Mazda insurance providers alongside conventional insurance companies.
So, Are Mazda MX-5s Cheap to Insure?
For many drivers, yes, an MX-5 can be surprisingly affordable to insure for a sports car.
However, there is no universal MX-5 insurance price.
Your age, driving experience, driving history, postcode, annual mileage, no-claims bonus and chosen model can make an enormous difference. Mazda MX-5 insurance groups also vary significantly between engines, generations and trim levels.
The best approach is to obtain several quotations for the exact Mazda MX-5 you are considering buying. That gives you a far more useful answer than relying on somebody else's average premium.
And remember that insurance is only one part of MX-5 ownership.
At MX5 City, we specialise in all things MX5, with specialist knowledge, cars, parts and support for owners of different generations of this iconic sports car.
