With 4 BMW 3 Series models currently available on Motoring Today, this popular saloon and estate offers a significant history of real-world UK MOT data to consider. Drawn from over 410,000 national DVSA MOT tests, the BMW 3 Series achieves a pass rate of 77.65%. While this figure reflects cars presented for test, not necessarily lifetime reliability, it provides a valuable benchmark. Bear in mind that MOT failures often cluster with a vehicle's age and how it's been maintained, rather than being solely a reflection of the badge itself. The most common failure category for the BMW 3 Series is 'Lighting & electrical', accounting for 27% of all faults. This is followed by 'Brakes' and 'Tyres', both responsible for 18% of failures, and 'Suspension' at 17%. For someone buying a used 3 Series, this means paying close attention to all exterior and interior lights, checking for correct operation, and ensuring no warning lights are illuminated. Crucially, verify the condition of brake discs, pads, and fluid, and inspect tyres for adequate tread depth and sidewall integrity, alongside checking suspension components for wear or leaks. We have a variety of BMW 3 Series listings for sale on Motoring Today, with prices starting from £9,999 or from a representative monthly payment of £242.
