BMW 4 Series Gran Coupe.
What to Check Before Buying.
The BMW 4 Series Gran Coupe blends coupe styling with four-door practicality, appealing to drivers who want executive presence without the full 5 Series footprint. Launched in 2014, it shares mechanical DNA with the 3 Series but attracts buyers seeking something more distinctive. Reliability is typical for modern BMW: generally solid, but timing chain wear on certain diesel engines and electronic niggles mean a thorough check of service history and MOT records is essential before committing.
