Used BMW M3 Buying Guide
The BMW M3 is the definitive fast saloon, and the used market spans three very different characters: the E90/E92 generation (2007-2013) with its screaming 4.0-litre V8, the F80 saloon (2014-2018) that went twin-turbo, and the current G80 (2021 on) with up to 500-plus bhp and optional xDrive. Each is a four-seat (or five-seat) family car that happens to be devastatingly quick, which is exactly why demand stays strong across every generation. The saloon bodystyle also makes the M3 the discreet choice next to its M4 coupe sibling - same hardware, lower profile on the street.
Engines and trims
The E90/E92’s S65 V8 revs past 8,000rpm and is the analogue experience, with manual or DCT gearboxes. The F80’s S55 twin-turbo straight-six brought huge mid-range punch, with Competition Package cars adding power and sharper chassis settings, and the limited CS at the top. The G80’s S58 offers around 473bhp standard (manual available) or 503bhp+ as a Competition with the eight-speed auto; Competition xDrive is the pragmatic UK all-seasons choice, and the Touring estate (G81) is the family-friendly unicorn. Options worth seeking: adaptive dampers, carbon-ceramic brakes (verify disc condition - replacements are very costly), head-up display and decent audio. Manual F80s and G80s are rarer in the UK and increasingly sought by collectors, while Competition automatics are the easy-to-live-with majority.
What to check before buying
Each generation has its homework. E90/E92: rod bearings are the famous S65 wear item - many cars have had them replaced preventatively, and paperwork proving it adds real value; throttle actuators are the other known failure. F80: the crank hub can slip on tuned cars, so favour standard examples or documented upgraded hubs, and check charge pipes and cooling system health. G80: strong so far, but insist on full digital service history and confirm any recall work.
Across all of them, the story matters as much as the car: consistent ownership, matching premium tyres, straight panel gaps and no hidden crash repairs. Ask directly about remaps and track days. A pre-purchase inspection by an M specialist is strongly recommended at every price point - these cars punish deferred maintenance. Check tyre dates as well as tread on low-mileage garage queens; old rubber on a 500bhp saloon is its own kind of false economy.
Running costs
None of them is cheap to run: fuel economy ranges from poor (V8) to merely acceptable (turbo cars on a motorway), insurance sits in the highest groups, and consumables - tyres, brakes, fluids - are the dominant cost for driven examples. Independent M specialists keep servicing sensible, and on E9x cars a rod-bearing fund (or proof of the job done) should be part of your budget. G80 values have settled from their early highs, making a used Competition a compelling alternative to far less capable new metal, while clean E92 manuals are quietly appreciating - condition-first buying serves both ends of the market.
Verdict
An M3 is a car you buy with your head fully engaged and enjoy with it switched off. The right example - standard, fully documented and independently inspected - is a deeply satisfying ownership experience in any generation; the wrong one will quietly become the most expensive saloon you have ever run. Choose history over price every time, without exception.
