Overview
BMW 02 Series E10 -Overview
The E10 is the BMW 02 Series, produced from April 1966 to July 1977 -the car that created the modern BMW sports saloon.
Based on a shortened version of the New Class sedans, the 02 Series established BMW's reputation for combining everyday usability with sporting performance. The range was powered exclusively by the M10 four-cylinder engine, designed by Baron Alex von Falkenhausen, in displacements from 1.6 to 2.0 litres. The 2002, introduced in 1968, became the icon of the range, while the 2002 Tii (1971) brought Kugelfischer mechanical fuel injection to the masses. The 2002 Turbo (1974) was BMW's first turbocharged production car, and the 1502 (1975) kept the 02 Series alive alongside the new E21 3 Series until 1977.

Best & Worst Engines

Best Value
M10B20 (2002, 2.0L single carburettor, 100 bhp)
“The base 2002 is the entry point to E10 ownership -100 bhp, 0-62 mph in 10.5 seconds, and a top speed of 173 km/h (107 mph). The single-carburettor engine is the simplest and cheapest to maintain, and the 2002's rising collector values make it a smart investment.”
Who it's for: buyers who want E10 ownership without the Tii or Turbo premium.

Highest Risk
M10B20 (22T A) (2002 Turbo, 2.0L turbocharged, 170 bhp)
“The 2002 Turbo is BMW's first turbocharged production car -170 bhp and 245 Nm of torque. It's a legend, but the turbocharger, unique engine management, and high-strung nature make it the most expensive and complex E10 to maintain. Only 1,672 were built.”
Who it's for: collectors and enthusiasts with deep pockets.

Most Expensive Failure
M10B20 (22T A) (2002 Turbo, 170 bhp)
“The 2002 Turbo's unique turbocharger, Bosch fuel injection, and low compression ratio (6.9:1) make it the most expensive E10 engine to rebuild -a full recon can exceed £7,500. Parts are scarce and specialist knowledge is essential.”
Who it's for: collectors willing to invest in a piece of BMW history.

Most Overlooked
M10B18 (1802, 1.8L, 90 bhp)
“The 1802 is often overlooked in favour of the 1602 or 2002 -but it's a sweet spot. More torque than the 1.6, better economy than the 2.0, and a lower entry price than the 2002. It's the thinking buyer's E10.”
Who it's for: buyers who want classic 02 Series character without the 2002 premium.

BMW 02 Series E10 -Ownership Economics
The E10 rule
A £2,200–£4,000 2002 recon against a £5,000–£25,000 E10 sits at 9–80% of the car's value【BMW-QUOTE】. On a sub-£8,000 example, that brushes our 70% BMW threshold -we'll honestly tell you to walk away. Against a well-kept £15,000+ example, the same recon drops to 15–27% -a repair decision, not a financial one. The E10's rising collector values mean a well-maintained car will justify engine work. For 2002 Turbo cars (£30,000–£60,000+), even the most expensive replacement is viable.
