BMW 4 Series

The BMW 4 Series coupe spans the sleek F32 (2014-2020) and the bolder, big-grilled G22 (2020 on) - the two-door, more style-led take on the 3 Series. Rear-wheel drive as standard with xDrive optional, it majors on a taut chassis and strong straight-six petrol and diesel engines. The G22's looks divide opinion, but underneath sits one of the best-driving cars in its class.

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.

Forecourt score

Value 71 · Reliability 37 · Insurance 9 · catalogue percentiles

The BMW 4 Series holds its value well and is dearer to run than most. Its MOT-based reliability is good — an MOT score of 73/100, ahead of 75% of the cars we track. On three-year value retention it ranks better than 71% 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.

At 37% BIK, a 40% taxpayer would pay about £660/month in company-car tax (£330/month at 20%) — on top of the running costs above. Full BIK table below for context.

Best age to buy — around 2 years

A 2-year-old example loses roughly £5,100 a year — 57% less than the £11,850 a one-year-old sheds. The steepest drop is behind it.

420i / 420d / 430i (4-cyl)

Indicative annual comprehensive premium estimates. The 'Typical' figure represents an average UK driver in each age band; Lower and Higher risk show the realistic spread driven by factors UK insurers legitimately price on (postcode, occupation, claims history, NCB, voluntary excess, modifications). Based on 10,000 miles/yr, £250 voluntary excess, and the no-claims bonus selected above. Always get individual quotes before buying.

MOT pass rate by age

A 3-year-old 4 Series passes its MOT 88.7% of the time; by 13 years that has slipped to 81%. The y-axis is zoomed to this model’s range so the trend is readable.

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

What fails at the first MOT

The defect categories a 4 Series registered 2020–2023 fails on at its first MOT, from 19,864 first tests. Every car here is the same age and the same generation, so these are the faults that show up first - not the wear a high-mileage older example collects.

Things owners say

  • 01The 420d diesel is the sweet spot for economy and torque; the 430i and six-cylinder M440i are the keen-driver picks.
  • 02xDrive all-wheel drive adds wet-weather security but a rear-drive car is the purer steer.
  • 03The F32's restrained styling has aged better than the G22's tall grille - largely a matter of taste.

Safety recalls

Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the BMW 4 Series, 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 4 Series 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.

Company car tax

What HMRC's Benefit-in-Kind charge looks like if you ran this BMW 4 Series as a company car, by tax year and income-tax band. Calculated from a CO₂ of 170 g/km, using £53,500 as the P11D value.

Tax yearBIK %Tax @ 20%Tax @ 40%Monthly @ 20%Monthly @ 40%
2025-2637%£3,959£7,918£330£660

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 4 Series, answered from the data

Is the BMW 4 Series reliable?
The BMW 4 Series scores 73/100 on Forecourt's MOT-based reliability measure, ahead of 75% of the cars we track. That is computed from 896,778 real DVSA MOT test results.
How much does a used BMW 4 Series cost?
A 2023 BMW 4 Series with around 28,032 miles is worth roughly £28,500 today (typical range £25,750–£31,250). Dealer forecourt prices sit higher and part-exchange offers lower; newer or lower-mileage examples cost more.
How quickly does the BMW 4 Series depreciate?
A new BMW 4 Series 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 4 Series?
The BMW 4 Series sits in insurance group 41 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 4 Series?
The most common age-related issues we track for the BMW 4 Series are: tyres & wheels (typically around over 100k miles, £80-£500 to put right); brakes (typically around over 100k miles, £150-£500 to put right); suspension (typically around over 100k miles, £150-£450 to put right). A full service history and a recent MOT with no advisories are the best protection.
What does the BMW 4 Series cost to run?
Expect around 44 mpg combined on the 420i M Sport, £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 4 Series ULEZ compliant?
Most petrol BMW 4 Seriess 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 4 Seriess are on UK roads?
About 113,913 BMW 4 Seriess 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.
