Ranked #69 car in the UK · Saloon · 9,906 units sold last year
The benchmark compact executive saloon. G20 (2019+) drives sweetly and feels tech-rich. 320d remains the long-distance king; 330e plug-in hybrid is the company-car favourite.
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
Forecourt score
Value 50 · Reliability 19 · Insurance 40 · catalogue percentiles
The BMW 3 Series holds its value about averagely and costs about average to run. Its MOT-based reliability is average — an MOT score of 65/100, ahead of 33% of the cars we track. On three-year value retention it ranks better than 50% of models. The main things to check on a used one are the timing chain (n47 diesel, pre-2014).
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 £556/month in company-car tax (£278/month at 20%) — on top of the running costs above. Full BIK table below for context.

A 5-year-old example loses roughly £3,100 a year — 56% less than the £7,100 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.

The budget entry to 3-series ownership. 184 PS petrol is unstressed and reliable — base SE is rare on the used market because most buyers ticked M Sport.
Watch for
The motorway-mile champion — 55 mpg makes diesel still make sense if you do 15k+ a year. Sport trim sits between SE and M Sport, with adaptive dampers.
Watch for
The volume seller — most used 3-series will be a 320i M Sport. Sweet petrol drivetrain but the M Sport pack pushes ride quality down on rough UK roads.
Watch for
M Sport's economy hero — combines diesel torque with the sharper look and chassis. The most failure modes to budget for, but also the longest legs.
Watch for
Plug-in hybrid that makes sense if you can charge at home — 36-mile EV range, ULEZ-compliant, lower BIK for company drivers. More to go wrong than ICE.
Watch for
The sweet spot for a fast 3-series — B58 inline-six is a gem, xDrive grips in winter. The most punishing on consumables but the most rewarding to drive.
Watch for
The full-fat M3 — 510 PS, 0-62 in 3.8s, holds value better than lesser 3-series. S58 had oil pump TSB attention — check service history closely.

How we estimate this
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.
Adjust the annual mileage to match how you'll actually use the car. Insurance is what you selected above (age 33-39, typical risk, 3 yrs NCB).

Euro NCAP's independent crash-test rating for the BMW 3 Series, from its 2019 assessment.
The passenger compartment of the 3-series remained stable in the frontal offset test.
Independent crash-test data from Euro NCAP. Star ratings reflect the test protocol of the year shown — newer protocols are stricter, so a 5-star from 2024 represents a higher bar than a 5-star from 2014. Euro NCAP ratings run for six years from publication; a lapsed rating means the protocol has moved on, not that the car performs any worse than it did on test.
How this model fares at its MOT as it ages — from 15,122,693 real DVSA test records.
MOT pass rate by age
A 3-year-old 3 Series passes its MOT 85.7% of the time; by 25 years that has slipped to 71.5%. The y-axis is zoomed to this model’s range so the trend is readable.
Longevity
From 35,209 vehicles registered in 2017.
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
The fuel-type split of every 3 Series with MOT history in the DVSA record. From 1,560,449 vehicles tested at least once - not the number on the road today, which is lower.
What fails at the first MOT
The defect categories a 3 Series registered 2020–2023 fails on at its first MOT, from 66,560 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.
Share of first MOT tests recording at least one defect in that category. DVSA test-item categories, not parts: “Driver’s view” covers mirrors, wipers and glass.
Typical mileage by age

Safety recalls
Manufacturers occasionally issue safety recalls to fix a fault free of charge. You can check whether the BMW 3 Series, or your exact vehicle, has any outstanding recalls on the official DVSA service.

A general indicator from UK 2025 theft data and this car’s characteristics — not a prediction for any one vehicle.
Whole-car theft
Higher
The BMW 3 Series is frequently targeted by thieves (UK 2025 data). Keyless entry on later cars makes relay theft the usual method.
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
Whether driving a BMW 3 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.
| City | Area | Daily charge | Likely outcome |
|---|---|---|---|
| London | All of Greater London (within the M25) | £12.50 | Likely exempt Diesel from September 2015 meets Euro 6. |
| Birmingham | Inside the A4540 Middleway | £8.00 | Likely exempt Diesel from September 2015 meets Euro 6. |
| Bristol | City centre and part of the Portway | £9.00 | Likely exempt Diesel from September 2015 meets Euro 6. |
| Glasgow | City centre | — | Likely exempt Diesel from September 2015 meets Euro 6. |
| Edinburgh | City centre | — | Likely exempt Diesel from September 2015 meets Euro 6. |
| Aberdeen | City centre | — | Likely exempt Diesel from September 2015 meets Euro 6. |
| Dundee | City centre | — | Likely exempt Diesel from September 2015 meets Euro 6. |

What HMRC's Benefit-in-Kind charge looks like if you ran this BMW 3 Series as a company car, by tax year and income-tax band. Calculated from a CO₂ of 164 g/km and a WLTP electric range of 60 miles, using £45,100 as the P11D value.
| Tax year | BIK % | Tax @ 20% | Tax @ 40% | Monthly @ 20% | Monthly @ 40% |
|---|---|---|---|---|---|
| 2025-26 | 37% | £3,337 | £6,675 | £278 | £556 |
| 2026-27 | 37% | £3,337 | £6,675 | £278 | £556 |

| 2029-30 | 39% | £3,518 | £7,036 | £293 | £586 |
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.
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.
