When BMW rolled out the 8-Series in the early 1990s, the E31 stood as the brand's most technologically ambitious grand tourer. This 1991 850i, currently listed on eBay out of Fayetteville, Arkansas, is a genuine European-market example built around the model's original 5.0-liter M70 V12. Rather than a turn-key driver, it is being offered as a stalled restoration project, complete with the parts removed during a since-interrupted repair.According to the seller, the car was purchased running and driving and was enjoyed for a time before a coolant leak sent it to a BMW specialist. Once there, the shop recommended replacing the head gaskets, and with the engine already opened up, additional preventative work was planned while everything was accessible. The project stalled before that work could be finished, and the 850i sat in storage for several years. It was brought home within the past year and has not been driven since.Under the disassembled hood sits the original 5.0-liter M70 V12, paired with a 4-speed automatic transmission and BMW's Automatic Stability Control plus Traction (ASC+T). The car retains its European-market details, including a metric instrument cluster showing 132,211 kilometers, or roughly 82,150 miles, along with heated memory seats, a power sunroof, and factory rear fog lights.Disassembled engine components and parts laid out from the BMW 850iBecause the restoration was interrupted mid-project, the listing notes that the major engine components, cylinder heads, and head-reassembly hardware are included, though the seller cautions the parts have not been formally inventoried and are being sold exactly as they have been stored. Also included are a custom strut tower brace made for the E31 platform, a set of original BMW indexed factory repair manuals, and the car's Arkansas title.Additional engine and suspension parts from the BMW 850i restoration projectThe seller describes the body as presenting well for its age, but not rust-free, with the kind of wear expected on a project car that has spent years off the road. The listing is explicit that the car is being sold as a complete project rather than parted out, offered as-is, and that pre-purchase inspections are welcome.AdvertisementAdvertisementClean, documented European-spec E31 850i's are becoming harder to find in the U.S. market, and this one gives a BMW enthusiast the chance to finish a restoration that is already partway underway. The car is listed at $7,495 or best offer, with a $250 deposit required for immediate payment.Photos and listing details courtesy of eBay seller thedudisnotin. View the original listing here.
