This 1988 BMW Alpina B10 3.5/1 is number 49 of 572 examples produced and previously resided in Japan and British Columbia before it was imported to the US. The car was previously sold on BaT in January 2020, and it was later acquired by the seller approximately three and a half years ago. Finished in Delphin Metallic over patterned black cloth upholstery, the car is powered by an Alpina-modified 3.5-liter M30 inline-six paired with a five-speed manual transmission. Equipment includes gold Alpina graphics, a replacement front Alpina spoiler, 17″ Alpina wheels, Alpina sport springs, Bilstein shocks, Recaro LS front seats, and dual-zone automatic climate control. Changes since the previous BaT listing include a five-speed manual transmission conversion, a replacement Alpina steering wheel, replacement exterior and interior trim pieces, reconditioned wheels, and paint correction. The digital odometer indicates 126k kilometers (~78k miles), approximately 1k kilometers of which were added under current ownership. This B10 3.5/1 is now offered with a clean Carfax report and a clean Texas title in the seller’s name.
The car is finished in Delphin Metallic and features gold Alpina graphics, fog lights, a sunroof deflector, Alpina badging, dual exhaust outlets, and a replacement front Alpina spoiler. The seller states that paint correction has been performed and worn exterior trim pieces have been replaced.
The staggered-width 17″ Alpina wheels were repaired and reconditioned in 2020 and are mounted with Continental ContiSportContact tires that were installed in preparation for the sale. The suspension is equipped with Alpina sport springs, and Bilstein shocks were installed in 2020. Braking is handled by four-wheel discs, and the brake fluid was exchanged in 2026.
The cabin features Recaro front seats upholstered in patterned black cloth with Alpina blue and green accent stripes along with black carpets and burl wood trim. Matching upholstery extends to the individual rear seats. Amenities include an onboard computer, dual-zone automatic climate control, and an aftermarket head unit. Multiple cosmetic trim pieces have been replaced, and the air conditioning system has been serviced. The seller notes the speakers are weak.
A plaque mounted on the center console identifies this car as number 49 of 572 B10 3.5/1 examples produced between 1988 and 1992.
The Alpina/MOMO replacement steering wheel frames a 260-km/h speedometer, a 7k-rpm tachometer, a fuel-economy gauge, and gauges for fuel level and coolant temperature. The digital odometer indicates 126k kilometers (~78k miles), approximately 1,000 kilometers of which were added under current ownership. The fuel level sender has been replaced.
The Alpina-modified, naturally aspirated 3.5-liter M30 inline-six features Mahle pistons, a modified cylinder head, a revised camshaft, revised Motronic engine management, and an Alpina exhaust system. Factory-rated output was 251 horsepower. The timing chain tensioner and associated gaskets are said to have been replaced following the previous BaT auction. An oil service was performed in 2025, and 2026 work included replacing the mass air flow sensor and battery as well as adjusting the throttle position sensor. The air conditioning condenser and drier have also been replaced.
Power is routed to the rear wheels through a five-speed manual transmission. The car was previously equipped with a four-speed automatic transmission, and the seller states that the five-speed manual gearbox was sourced from a 1992 E34 donor car, resealed, and installed in late 2020. Documentation related to the transmission conversion is included in the sale.
The Carfax report shows history in British Columbia and Pennsylvania.
