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.
