Is the BMW M3 reliable?

The BMW M3 scores 89/100 on Forecourt's MOT-based reliability measure, ahead of 32% of the cars we track. That is computed from 452,250 real DVSA MOT test results.

How much does a used BMW M3 cost?

A 2023 BMW M3 with around 21,933 miles is worth roughly £53,250 today (typical range £46,800–£59,700). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.

How quickly does the BMW M3 depreciate?

A new BMW M3 typically loses about 30% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.

What insurance group is the BMW M3?

The BMW M3 sits in insurance group 32 of 50 — the more expensive end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.

What goes wrong on a used BMW M3?

The most common age-related issues we track for the BMW M3 are: suspension (typically around over 100k miles, £150-£450 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right); brakes (typically around over 100k miles, £150-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.

What does the BMW M3 cost to run?

Expect around 28 mpg combined on the M3 Competition xDrive, £200 a year in road tax, about £290 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.

Is the BMW M3 ULEZ compliant?

Most petrol BMW M3s from 2006 and diesels from September 2015 meet the Euro standards for London ULEZ and other UK clean-air zones, so they are generally exempt from the daily charge. Pure-electric versions are always exempt.

How many BMW M3s are on UK roads?

About 27,883 BMW M3s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

BMW M3

The BMW M3 spans the F80 (to 2018) and the big-grilled G80 (2021 on) - the benchmark super-saloon, now offered with rear- or xDrive four-wheel drive and even a Touring estate abroad. Its twin-turbo straight-six is a masterpiece, and the G80 added everyday usability to the old car's edge. Divisive looks aside, it remains one of the most complete fast four-doors you can buy.

How these figures are sourced — the valuation is anchored to a researched used-market price for this model (AutoTrader median, 2023 at 30k miles). Reliability, mileage and variant data are real DVSA MOT records. Dimensions, tyre sizes and costs, servicing figures and the insurance group are segment-level estimates rather than sourced per car, and are being replaced model by model.

The short version

91/100

Forecourt score

Value 93 · Reliability 89 · catalogue percentiles

The BMW M3 holds its value well and is dearer to run than most. Its MOT-based reliability is excellent — an MOT score of 89/100, ahead of 32% of the cars we track. On three-year value retention it ranks better than 93% of models.

The Forecourt score blends how this car ranks against the catalogue on value retention, reliability and insurance cost (weighted 40/40/20) — the from-new ownership picture. Higher is better; running cost is not yet folded in.

Things owners say

01The straight-six is superb; the Competition is the one most chase, with xDrive for all-weather pace.
02The G80's grille splits opinion, but it's roomier and more usable daily than the focused F80.
03Manuals exist on rear-drive G80s for purists; most are the quicker, smoother eight-speed auto.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the BMW M3, or your exact vehicle, has any outstanding recalls on the official DVSA service.

Check on GOV.UK

Opens the Driver & Vehicle Standards Agency recall checker. Choose the make, model and year of manufacture — no registration needed.

Theft risk

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.

Whole-car theft

Higher

Higher-value cars like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.

Parts theft

Around average

Parts-theft risk is around average — catalytic-converter theft is the main thing to be aware of on any petrol or diesel car.

Worth doing

Keep keys in a Faraday pouch and away from the front door to block relay attacks.
A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.

Clean-air zones

Whether driving a BMW M3 into a UK clean-air zone will cost you anything. Rules use the same Euro standard across most zones — petrol from 2006 and diesel from 2015 onwards are exempt; pure electric is always exempt.

Charging zones for cars

City	Area	Daily charge	Likely outcome
London	All of Greater London (within the M25)	£12.50	Likely exempt Petrol from 2006 meets Euro 4.
Birmingham	Inside the A4540 Middleway	£8.00	Likely exempt Petrol from 2006 meets Euro 4.

Company car tax

What HMRC's Benefit-in-Kind charge looks like if you ran this BMW M3 as a company car, by tax year and income-tax band. Calculated from a CO₂ of 233 g/km, using £97,500 as the P11D value.

Tax year	BIK %	Tax @ 20%	Tax @ 40%	Monthly @ 20%	Monthly @ 40%
2025-26	37%	£7,215	£14,430	£601	£1,203
2026-27	37%	£7,215	£14,430	£601	£1,203

2029-30	39%	£7,605	£15,210	£634	£1,268

P11D value is approximated from the latest new price; the exact figure on your tax code will depend on options fitted. The 4% diesel surcharge applies only to non-RDE2 (pre-2021) diesels — we assume RDE2 compliance for current models. Bands and rates from HMRC's Autumn Budget 2024 confirmation through 2029/30.

Servicing & the dealer network

How well-supported BMW is across the UK — a practical read on how easy servicing, parts and warranty work will be to find.

Franchised UK dealers

Large network

Premium mainstream

Network size relative to the UK's largest (BMW is 3.2% of all franchised outlets)

Servicing, parts and warranty work are easy to find UK-wide, and most independent garages know the brand well — which keeps maintenance competitive.

For context, the UK has roughly 4,500 franchised car-dealer outlets in total, plus about 15,500 independent garages.

Approximate figures, curated from public UK industry sources (NFDA, Car Dealer Magazine). Franchised networks shrink year on year — these indicate network size, not an exact count.

Common questions

BMW M3, answered from the data

Is the BMW M3 reliable?: The BMW M3 scores 89/100 on Forecourt's MOT-based reliability measure, ahead of 32% of the cars we track. That is computed from 452,250 real DVSA MOT test results.
How much does a used BMW M3 cost?: A 2023 BMW M3 with around 21,933 miles is worth roughly £53,250 today (typical range £46,800–£59,700). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the BMW M3 depreciate?: A new BMW M3 typically loses about 30% of its value over the first three years, then depreciates more slowly. Buying at three to five years old avoids the steepest part of the curve.
What insurance group is the BMW M3?: The BMW M3 sits in insurance group 32 of 50 — the more expensive end of the scale. Exact premiums depend on the trim (some versions sit a few groups higher or lower), your age, postcode and no-claims history.
What goes wrong on a used BMW M3?: The most common age-related issues we track for the BMW M3 are: suspension (typically around over 100k miles, £150-£450 to put right); tyres & wheels (typically around over 100k miles, £80-£500 to put right); brakes (typically around over 100k miles, £150-£500 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the BMW M3 cost to run?: Expect around 28 mpg combined on the M3 Competition xDrive, £200 a year in road tax, about £290 for a standard annual service. The full cost-of-ownership table above breaks this down per year and per mile for the exact year and mileage you choose.
Is the BMW M3 ULEZ compliant?: Most petrol BMW M3s from 2006 and diesels from September 2015 meet the Euro standards for London ULEZ and other UK clean-air zones, so they are generally exempt from the daily charge. Pure-electric versions are always exempt.
How many BMW M3s are on UK roads?: About 27,883 BMW M3s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.

Answers are generated from this car's Forecourt data — DVSA MOT records, DfT licensing statistics and our valuation model — and update with the weekly data refresh.
