2018 BMW 4 SERIES 2.0 420d Xdrive M Sport Coupe

The BMW 4 Series, first launched in 2013, represents a sportier, more dynamic evolution of the 3 Series saloon, available as a sleek coupé, a stylish convertible, and the practical Gran Coupé. Known for its engaging driving dynamics, premium interior, and sophisticated styling, it appeals to those seeking a balance of luxury, performance, and everyday usability in a more distinctive package than its saloon counterpart. Whether you're after a thrilling two-door or a practical four-door coupé, the 4 Series offers a compelling proposition for discerning UK drivers.

Typical Price Range

All prices are approximate and subject to change based on condition, mileage, specification, and market conditions.

• 2013–2016: £9,000 – £16,000 — Early first-generation models, offering significant value. Prices are approximate and depend heavily on mileage and condition.
• 2017–2020: £15,000 – £25,000 — Facelifted F32/F33/F36 models, often with updated tech and minor styling tweaks. Prices are approximate and subject to market conditions.

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.
• iDrive system glitches or software freezes, often resolved with dealer updates.
• 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.
• 435d/440i xDrive: For those who demand serious performance and sure-footed grip in all weathers. These powerful six-cylinder engines provide exhilarating acceleration, while xDrive (all-wheel drive) enhances stability. Less economical but highly rewarding for enthusiasts.
• 4 Series Convertible: A lifestyle choice for drivers who love open-air motoring. While slightly heavier and less rigid than the coupé, it offers an incomparable driving experience on a sunny day. Best for leisure and occasional use, though perfectly capable as a daily.
• M4 Competition: The pinnacle of the 4 Series range, built for driving purists and track-day enthusiasts. Offers supercar-rivalling performance, aggressive styling, and a track-focused chassis. Best suited for experienced drivers seeking an uncompromised high-performance machine.
