About the BMW 8 Series
The 8 Series nameplate has appeared across three distinct generations. The original E31 (1989-1999) was a technological showcase featuring V8 and V12 engines, pop-up headlights and advanced electronics. After an 18-year hiatus, BMW revived the model with the F92 concept before launching the current G15 generation in 2018. Available as a Coupé, Convertible or four-door Gran Coupé, modern 8 Series models offer petrol and diesel powertrains ranging from the 840d to the M8 Competition, with outputs from 316bhp to over 600bhp. Standard equipment includes leather upholstery, digital instrumentation, adaptive suspension and comprehensive driver assistance systems.
What Affects the Price of a Used BMW 8 Series
Generation is the primary price determinant. E31 models from the 1990s now trade between £8,000 and £30,000 depending on condition and specification, with 850CSi and 850i V12 variants commanding premiums. Current G15 models (2018 onwards) start around £35,000 for early 840d examples, rising to £55,000 or more for M850i and M8 variants. Mileage significantly impacts value, with sub-30,000-mile examples fetching 15-20% premiums over higher-mileage counterparts. Body style affects pricing, with Gran Coupé models typically £2,000-£4,000 more expensive than equivalent two-door Coupés, whilst Convertibles sit at the top of the range. Specification plays a crucial role—M Sport packages, carbon ceramic brakes, Bowers & Wilkins audio and individual colour options all add value. Full BMW service history is essential, particularly for G15 models still under warranty.
Tips for Buying a Used BMW 8 Series
For E31 models, inspect electronics thoroughly as components can be difficult to source. Check for corrosion around wheelarches and sills, and verify V12 engines have complete service histories. Budget for specialist maintenance as parts availability is limited. With G15 models, prioritise examples with remaining manufacturer warranty or approved used status. Verify all electronic systems function correctly—faults with the digital dashboard, cameras or adaptive cruise control can be costly to rectify. Check for tyre wear on the inner edges, indicating suspension geometry issues common with lowered M Sport variants. Examine service records for oil changes and brake fluid replacements at correct intervals. M Performance models should have documented evidence of differential and transmission servicing. Consider independent pre-purchase inspections, particularly for high-performance M8 variants where consumable costs are substantial. Test the adaptive suspension across all modes and listen for compressor noises indicating potential air suspension faults.
