Common Issues to Check
- Timing chain issues in early N47 diesel engines (pre-2015), though many will have been resolved or are on higher mileage cars.

- Wear and tear on suspension components (bushes, dampers) on higher mileage models, affecting ride comfort.
- Potential for water ingress in older convertible models if drains become blocked or seals degrade.
- Electrical gremlins, such as faulty sensors or dashboard warning lights, are not uncommon on any complex modern car.
Running Costs
- Fuel Economy: 30-55 mpg depending on engine and driving style (e.g., 420i around 40 mpg, 420d around 55 mpg, M4 up to 30 mpg).
- Insurance Group: Typically ranges from Group 25 to Group 45, with M Performance models being higher. Always check the specific vehicle's VIN for an accurate quote.
- Servicing: Generally moderate to high, in line with a premium marque. Expect annual service costs ranging from £200-£500+ for routine maintenance, with major services or specific repairs costing more. Specialist BMW garages can offer more competitive pricing than main dealers.
Which Variant Should I Choose?
- 420i/430i Coupé: Perfect for drivers seeking a blend of sporty handling and accessible performance, without sacrificing too much on fuel economy. Ideal for daily commuting and weekend blasts.
- 420d Gran Coupé: The ultimate all-rounder for families or business users. Offers the practicality of four doors and a hatchback, combined with excellent diesel fuel economy and still engaging to drive. Great for longer journeys.
