Used BMW 1 Series Buying Guide
The BMW 1 Series has long been the entry point into BMW ownership, and the used market offers three distinct takes on the idea. The E87-generation cars (2004-2011) and the F20 (2011-2019) are rear-wheel drive — unique among premium hatchbacks — while the current F40 shape (2019 onwards) switched to front-wheel drive, trading a little of that engineering novelty for noticeably better rear-seat and boot space. All three deliver a more upmarket feel than mainstream hatchback rivals, which is exactly why they hold their appeal second-hand.
Engines and trims
Petrol choices run from modest 116i and 118i units through to the six-cylinder M135i and M140i hot hatches of the F20 era, which are performance bargains in their own right. The current 118i uses a turbocharged three-cylinder that suits town and mixed driving well, while the F40 M135i xDrive moves to a powerful four-cylinder with all-wheel drive. Diesels — 116d, 118d and 120d — dominate higher-mileage stock and remain excellent motorway companions, with the 120d offering the best blend of pace and economy for long-distance drivers.
Trim levels follow the familiar BMW ladder: SE covers the essentials, Sport adds styling and larger wheels, and M Sport — comfortably the most common on used forecourts — brings firmer suspension, sportier seats and the bodykit most buyers want. Desirable options include navigation (standard on later cars), heated seats and parking sensors. On M Sport cars, adaptive dampers are worth seeking out because the standard sports suspension can feel firm on run-flat tyres.
What to check before buying
The best-known issue affects the diesels. The N47 engine fitted to E87 and earlier F20 diesels — roughly up to 2014-15 — can suffer timing chain wear, and because the chain sits at the rear of the engine, replacement is an engine-out job with a bill to match. Listen carefully for a metallic rattle or tinkling from the back of the engine at idle and on a cold start; walk away or negotiate hard if you hear it. Later B47 diesels are considerably more robust in this respect. Diesel 1 Series were also included in BMW’s EGR cooler recall, so confirm through a dealer that any outstanding recall work has been completed.
Beyond that, check the service history is complete, look for evidence of regular oil changes on turbocharged petrols, and make sure the iDrive system, Bluetooth and any driver assistance features all function. On rear-wheel-drive cars inspect rear tyres for uneven wear, and on any example be alert for crashed-and-repaired bodywork — these are popular cars with younger drivers. Short-trip diesels can present blocked particulate filters, so favour cars with a motorway life. Finally, drive over rough surfaces: run-flat tyres transmit more noise and fidget than conventional rubber, and worn suspension bushes exaggerate it.
Running costs
Running costs are one of the 1 Series’ strengths. The diesels are genuinely economical, the three-cylinder petrols respectably so, and insurance for mainstream versions sits in moderate groups — though the M135i and M140i are a different, costlier conversation. Servicing at a BMW dealer costs more than mainstream rivals, but a good independent BMW specialist narrows the gap considerably, and parts availability is excellent. Budget extra for run-flat tyre replacement, which costs more than standard equivalents.
Verdict
A used 1 Series offers a premium badge and genuinely good driving manners at family-hatchback money. Buy an F20 or E87 diesel only after listening hard for chain rattle and confirming recall work; buy an F40 if practicality matters most. Well-maintained examples of any generation make a satisfying, sensible step up from mainstream hatchbacks.
