BMW 4 SERIES (F3X) 428I M SPORT GRAN COUPE 2015

2015 BMW 428i Gran Coupe M Sport – Stage 2 Tuned – 101,000 miles

Selling my pride and joy due to needing a bigger car for three kids. This car has been well looked after, with regular servicing at BMW up until [insert date/year]. Since then, I’ve done the servicing myself – oil and filter were changed just 2,000 miles ago. Rear brake pads were replaced a month ago, and brand-new NGK spark plugs have just been fitted.

✅ 12 months MOT

✅ Extensive maintenance history

✅ Over £5,000 in tasteful performance and cosmetic upgrades

The car looks and sounds like an M car thanks to the mods. It’s been incredibly reliable – the only issue I’ve had was an alternator belt failure a few months ago, which has since been replaced with a brand-new one.

As expected for a car of this age and mileage, there are a few light scuffs and small dents, but nothing major – overall, it still presents really well and turns heads.

These engines are known to last up to 150,000 miles when properly maintained – so there’s still plenty of life left in it!
