Launched for the 1990 model year, the E31 8 Series was BMW's flagship grand tourer. It was a technological showcase, featuring advanced systems like a drive-by-wire throttle and a multi-link rear axle. Buyers could choose between a smooth V8 (840Ci) or the imposing V12 (850i/Ci/CSi), cementing its status as a top-tier GT car.
Collectors are primarily drawn to the original E31 generation for its iconic 90s design, which includes pop-up headlights and a pillarless hardtop profile. The ultra-rare 850CSi, with its M-developed 5.6L V12 and 6-speed manual gearbox, is the most sought-after model. While the modern G15 8 Series revived the nameplate in 2018, the E31's unique character defines its collector appeal.
The 8 Series market is broad, with an average sale price of $43,205 across 471 transactions. Project-level E31s can be found for under $10,000, but they often hide immense maintenance costs. Well-kept 840Ci and 850Ci examples trade between $20,000 and $50,000, while pristine 850CSi models can exceed $150,000.
Buying Tips
- The E31's complex electronics were advanced for the era; test all functions, as diagnosing issues with the General Module or instrument cluster can be costly.
- On V12 models, check for oil leaks from the valve covers and timing case covers, and ensure the engine runs smoothly on all 12 cylinders, as it uses dual fuel and engine management systems.
- Inspect the suspension carefully. Early cars had EDC electronic dampers that are expensive to replace, and many have been converted to conventional shocks.
- Look for rust in the rocker panels, wheel arches, and floor pans, which can result from leaky window and sunroof seals on the pillarless body.
Prices range from $1,295 for project cars to $349,999 for top-spec modern variants and collectible 850CSi models.
