EDITORIAL PULL-QUOTE
The One Thing We'd Tell Every BMW 2002 Buyer
“If you buy one 2002 based on this page, buy the best-documented 2002tii you can afford - the Kugelfischer-injected M15 is the sweet spot: 130 hp, mechanical fuel injection, and the most desirable non-Turbo 2002. If the Turbo is calling you, budget for specialist KKK turbo and Kugelfischer restoration - only 1,672 were built, and they're only going one way. On any 2002, a documented M10 rebuild with timing chain and cooling system work is worth more than any service stamp.”

Who Should Buy a BMW 2002?
Different buyers, different priorities. Here’s our verdict on who the 2002 is perfect for - and who should think twice.
Different buyers, different priorities. Here’s our verdict on who the 2002 is perfect for - and who should think twice.
The 2002 is a rising classic - the tii is the sweet spot, the Turbo is the ultimate collectible. Both are appreciating assets. Buy the best-documented example you can afford.
Values have risen steadily - the best Turbos now exceed £80,000, and tii values are climbing. The 2002 is a preservation asset, not a depreciating car.
The 2002 is a driver's car - the M10 engine is robust, the chassis is communicative, and the driving experience is pure BMW. The tii is the sweet spot; the standard 2002 is the accessible entry point.
Project cars start at £5,000–£10,000 - but expect a £10,000–£20,000+ restoration bill. The M10 engine is rebuildable, but rust is the real enemy. Buy the best shell you can afford.
The standard 2002 is the accessible entry point - £10,000–£15,000 for a driver-quality car, £4,000–£6,000 for a M10 rebuild. The 2002 is a manageable classic for a first-time buyer.

BMW 2002 Frequently
Asked Questions
A standard M10 rebuild typically costs £4,000–£6,000 supply only [PATTERN DATA]. A tii rebuild costs £6,000–£10,000+; a Turbo rebuild costs £8,000–£12,000+. Fitting and specialist labour add significantly. Use our calculator for a personalised assessment.
The 2002 is powered by the M10 - a 1,990 cc inline-four petrol engine. The standard 2002 produces 100 hp; the ti produces 120 hp; the tii produces 130 hp; the Turbo produces 170 hp.
The M10 is one of BMW's most durable engines - over 3.5 million were produced across many models. However, age-related issues (cooling system, timing chain, Kugelfischer injection) require specialist attention. A well-maintained M10 can last hundreds of thousands of miles.
By issue: rattling on startup (timing chain stretch), uneven running (Kugelfischer injection synchronisation on tii/Turbo), overheating (cooling system deterioration), water in oil (cylinder head cracking). On the M10, any running issue is a warning sign. Caught early, it's a service; ignored, it's a £4,000–£12,000+ rebuild.
Depends on the model. Against a £25,000–£40,000 tii, a £6,000–£10,000+ rebuild is 15–40% - a worthy investment. Against a £60,000–£80,000+ Turbo, a £8,000–£12,000+ rebuild is 10–20% - a worthy investment. Against a £10,000–£15,000 standard 2002, a £4,000–£6,000 rebuild is 27–60% - ⚠️ watch on cheaper cars.
2002tii with the M15 - the sweet spot: 130 hp, Kugelfischer mechanical fuel injection, and the most desirable non-Turbo 2002. For the ultimate collectible, 2002 Turbo - Europe's first turbocharged production car, only 1,672 built. For the accessible entry point, standard 2002 - £10,000–£15,000 for a driver-quality car.
Listed on the VIN plate and in the vehicle documentation; the block stamping is visible from the driver's side. The 2002 uses the M05, M10, M15, M31 or M115 engine codes depending on the model.
The 3.0 CSL is the more collectible of the two - only 1,265 CSLs were built, compared to 401,947 2002s. The CSL is a six-figure classic; the 2002 is a rising classic that is more accessible. Both are BMW icons and worthy investments. Read the full head-to-head →
