1990 BMW 535i Hartge H5SP

Tech

This 1990 Hartge H5SP is based on an E34 535i and spent time in Canada before being brought to the US in 2018. Power comes from a Hartge-modified and rebuilt 3.4L M30B35 inline-six linked to a four-speed automatic transmission, and model-specific features include a body kit, a rear spoiler, side stripes, multi-piece 16” wheels, and a front strut tower brace. The interior is trimmed in black leather upholstery with burl wood accents, and amenities include an Italvolanti steering wheel, a power sunroof, dual-zone automatic climate control, heated front seats, cruise control, an onboard computer, and a Continental digital media receiver. This H5SP was acquired by the seller on BaT in February 2026 and is now offered with a clean Carfax report and a clean California title in the seller’s name.
