1992 BMW 325i M-Technic Convertible E30 3-Series

This 1992 BMW 325i M-Technic convertible was acquired by the seller in 2013 and underwent an EV conversion in 2019. The car is powered by two Chevrolet Volt lithium-ion batteries linked with a Tesla Model S large drive unit powering the rear wheels through a single-speed transmission and a Quaife limited-slip differential. Components include an Openinverter controller, a 10-kW onboard charger, a J1772 charging port, and a Tesla Model S cooling system and iBooster electric brake booster. Additional equipment consists of the M-Technic Appearance Package, a 1.5-kW cabin heater, hard and soft tops, Ireland Engineering coilovers, 17″ Apex wheels, Ground Control camber/caster plates, an M-Tech II steering wheel, a rotary touch gear selector, and upgraded audio components. This E30 convertible is now offered at no reserve with an OpenEVSE 48-amp level 2 charger unit, a clean Carfax report, and a clean Connecticut title in the seller’s name. The car is finished in Alpine White II and features a black convertible soft top converted to operate manually as well as a black hardtop. The kidney grilles flip-up to reveal a J1772 charging port, and the optional M-Technic Appearance Package added special front and rear valances as well as side skirts and extended rocker, covers. Work performed under current ownership is said to have included replacing the taillamps, removing the headliner, and installing LeoGrande Racing billet aluminum door handles. The trunk and hood were replaced, and blemishes include door dings, peeling clear coat on the bumpers, a repainted area on the driver-side fender, rock chips, and rust around the rear tow hook. Multi-spoke 17×8.5″ Apex ARC-8 wheels are mounted with 255/40 Falken Azenis RT615K tires and the fenders were rolled for clearance. A Volvo electric power steering pump is said to have been installed along with Ground Control camber/caster plates, Ireland Engineering coilovers, a 25-millimeter front sway bar, a strut brace, lowering springs, Condor Speed front control arm bushings, and replacement rubber trailing arm bushings. The rear tires rub the fenders under load, and braking is assisted by a Tesla iBooster and a regen motor. A spare wheel is included in the sale. The interior was refreshed under current ownership with M-Rain style cloth upholstery, replacement carpets, and a “flocked” dashboard. Additional work included installing a touchscreen Bluetooth-capable stereo, a Blaupunkt amplifier, under-seat subwoofers, door pull straps, a wireless phone charger, and a Grayhill rotary-touch encoder which controls gear selection and window functions. The ignition was re-keyed, the air conditioning system was removed, and a 1.5kW cabin heater has been retrofitted to operate using the factory controls. The M-Tech II steering wheel was recovered by AZA Auto Wheel and frames a custom cluster with gauges for battery power and amperage. The six-digit odometer shows 186k miles, approximately 100k of which were added by the seller. Total mileage is unknown. The electronic vehicle control module features a launch function.
