BMW X6
The BMW X6 (G06, 2018 on) is the original coupe-SUV concept at full size - the swept-roof sibling to the X5, trading practicality for presence and pace. Petrol and mild-hybrid straight-sixes and V8s give serious performance, with the X6 M at the top. It's a big, fast, image-led statement rather than a sensible family hauler; the X5 is the rational choice, the X6 the one bought with the heart.
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.

Best age to buy — around 4 years
A 4-year-old example loses roughly £7,050 a year — 52% less than the £14,700 a one-year-old sheds. The steepest drop is behind it.
Uses current UK pump and home-charging prices (DESNZ weekly), typical-driver insurance and manufacturer service intervals. "Fuel per mile" is just the energy input — so an EV at ~9p and a diesel at ~22p make running-cost comparison direct. A guide; your own costs will vary.

MOT outlook
How this model fares at its MOT as it ages — from 181,899 real DVSA test records.
MOT pass rate by age
A 3-year-old X6 passes its MOT 87.2% of the time; by 18 years that has slipped to 78.2%. The y-axis is zoomed to this model’s range so the trend is readable.
Longevity
From 2,285 vehicles registered in 2018.
Survival by registration year
Each point is one registration cohort. Older cars on the left, newer on the right. A flatter line means the model holds up over time; a steep drop means cohorts disappear from UK roads faster.
What’s on the road

Things owners say
- 01The petrol and mild-hybrid sixes suit most; the V8 M cars are the rapid, thirsty flagships.
- 02The coupe roofline cuts rear headroom and boot space sharply versus the X5 - it's a style buy.
- 03Air suspension and big wheels mean real running costs - check suspension health on older cars.
Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the BMW X6, or your exact vehicle, has any outstanding recalls on the official DVSA service.
Check on GOV.UKOpens 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
Desirable SUVs like this are relay-theft targets — keyless entry can be exploited from the driveway in under a minute.
Parts theft
Higher
Hybrid versions are a catalytic-converter target — a hybrid cat is rich in precious metals and can be cut out in about a minute.
Worth doing
- Keep keys in a Faraday pouch and away from the front door to block relay attacks.
- A catalytic-converter guard or forensic marking makes a hybrid far less appealing to cut.
- A visible steering lock is a cheap, strong deterrent on a frequently-targeted car.
Clean-air zones
Whether driving a BMW X6 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. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Petrol from 2006 meets Euro 4. |
| Glasgow | City centre | — | 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 X6 as a company car, by tax year and income-tax band. Calculated from a CO₂ of 227 g/km, using £90,000 as the P11D value.
| Tax year | BIK % | Tax @ 20% | Tax @ 40% | Monthly @ 20% | Monthly @ 40% |
|---|---|---|---|---|---|
| 2025-26 | 37% | £6,660 | £13,320 | £555 | £1,110 |
| 2026-27 | 37% | £6,660 | £13,320 | £555 | £1,110 |
| 2027-28 | 38% | £6,840 | £13,680 | £570 | £1,140 |
| 2028-29 | 39% | £7,020 | £14,040 | £585 | £1,170 |
| 2029-30 | 39% | £7,020 | £14,040 | £585 | £1,170 |
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
~145
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 X6, answered from the data
- Is the BMW X6 reliable?
- The BMW X6 scores 65/100 on Forecourt's MOT-based reliability measure, ahead of 65% of the cars we track. That score uses first-MOT pass rate and defect rate for cars registered 2018 onward (7,357 first tests), with cohort survival — high confidence.
- How much does a used BMW X6 cost?
- A 2023 BMW X6 with around 29,421 miles is worth roughly £41,950 today (typical range £36,600–£47,250). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
- How quickly does the BMW X6 depreciate?
- A new BMW X6 typically loses about 36% 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 X6?
- The BMW X6 sits in insurance group 31 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 X6?
- The parts most often recorded at MOT on the BMW X6 are: tyres & wheels (typically around 60k-100k miles, £80-£500 to put right); suspension (typically around over 100k miles, £150-£450 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 X6 cost to run?
- Expect around 42 mpg combined on the X6 xDrive30d, £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 X6 ULEZ compliant?
- Whether a BMW X6 is ULEZ compliant depends on its engine and registration date: petrol from 2006 and diesel from September 2015 generally qualify, and electric versions are always exempt.
- How many BMW X6s are on UK roads?
- About 16,600 BMW X6s are currently taxed and on the road in the UK, from DfT vehicle-licensing data.
