Overview of the BMW 3
The 3 Series is German car maker BMW's signature model - a compact luxury passenger car that has existed in multiple generations since its 1975 debut.
Since 2014, the 3 Series name has applied to sedan and wagon body styles only, with coupe and convertible models adopting the 4 Series nomenclature.
The 3 Series has long been considered one of the most entertaining cars to drive in its class, and the flagship M3 performance variant is especially famous.

WHAT TO LOOK OUT FOR: BMW 3 SERIES
As with any high-end European car, don't go near a 3-Series that doesn't have a fully stamped service history.
Biggest potential grief comes from variable valve-timing system (VANOS, in BMW-speak) which can fail due to internal leaks within the hydraulic circuitry. Some six-cylinder 3-Series were even recalled to fix this.
Beyond a leak, VANOS can fail through a lack of oil changes as dirt and grit blocks the tiny oilways that operate the system. If it fails, it can cost thousands to fix and the car won't be right without it.
Any 3-Series showing a 'check-engine' light on the dash is cause for concern.
Some early cars from this series had a brake booster that could fail, leaving the car with brakes but no assistance, requiring the driver to press harder on the brake pedal.
Again, this was the subject of a recall, so check that it's been done on affected cars.
