The 1-Series is the smallest range in BMW's arsenal. Competing in a peculiar segment defined by expensive small cars, the 1-Series is the only vehicle in its class featuring rear-wheel-drive. First offered in mid-2004 as a 5-door hatchback using its own platform, it replaced the slow-selling 3-Series Compact. Facelifted for 2008, the five-door hatchback was joined by a three-door hatchback. The range was soon expanded to include a two-door coupe and a two-door convertible. Petrol versions now include the 2.0-litre 118i, the 2.0-litre 120i, the 3.0-litre 125i and the 3.0-litre turbocharged 135i, although the higher engines are reserved for the two-door models. In 2009, a basic 120i convertible debuted. All models come with a choice of 6-speed transmissions, both manual or automatic. In late 2011, a limited-edition 1M Coupe was offered with a 3.0-litre turbo 6-cylinder and manual only. While the hatchback was completely redesigned for 2012, the coupe and convertible continued unchanged for one more year. All non-M trims come standard with common power accesories, cloth or leather upholstery, front and side airbags, stability control and ABS, alongside various optional features such as HID headlights, "active" steering, stereo choices and various wheel sizes. Considering the price, the way it looks, and the number of these seen on the streets, BMW is having trouble moving these off the showroom floor in this region.
Check if all electronics working. Few complain of window water-leaks in car wash. Common reports include burnt-out tail-lamps and odd transmission behaviour requiring software reflash. BMW issued recall for high-pressure fuel pumps involving 135i turbo models in many countries following late-2010 negative publicity.
