21-Years-Owned 1984 Ferrari 308 GTSi Quattrovalvole

This 1984 Ferrari 308 GTSi Quattrovalvole has remained registered in Arizona and California since new and was purchased by the seller from its second owner in 2004 as a birthday gift for his wife. Powered by a 2.9-liter quad-cam V8 paired with a five-speed manual transaxle, the car is finished in Rosso Corsa over beige leather upholstery. Equipment includes a limited-slip differential, 16″ five-spoke alloy wheels, a removable roof panel, pop-up headlights, a quad-exit exhaust system, air conditioning, an aftermarket head unit, a gated shifter, and electric windows. Work performed since 2024 has included reupholstering the seats, adjusting the valves, and replacing the timing belts, water pump, camshaft seals, valve cover gaskets, spark plugs and wires, fuel pump, steering rack, and brake pads and rotors. This 308 GTSi Quattrovalvole shows 63k miles and is offered with manufacturer’s literature, service records, a tool kit, spare parts, a clean Carfax report, and a clean Arizona title in the seller’s name.

The car is finished in Rosso Corsa and features a black removable roof panel, pop-up headlights, dual side mirrors, a vented decklid, and quad exhaust outlets. A ding in the roof and a bend in the driver-side of the hood near the locking latch are noted by the seller. Close-up photos of exterior paint blemishes are shown in the gallery below.

Silver 16″ five-spoke alloy wheels are mounted with Bridgestone Potenza tires. The car features a fully independent suspension with double wishbones front and rear, and stopping power is provided by ventilated discs at each corner. The shocks were replaced and the ride height was adjusted in 2016, and work in 2024 included replacing the brake pads and rotors, brake hoses, sway bar bushings, and steering rack.

The cockpit features bolstered seats that were reupholstered in beige leather upholstery in 2025. Equipment includes air conditioning, an aftermarket stereo, electric windows, and a gated shifter with a dogleg gear pattern.

The leather-wrapped MOMO steering wheel fronts Veglia instrumentation including a 180-mph speedometer, a tachometer with a 7,700-rpm redline, and supplementary gauges. Additional readouts are mounted ahead of the shifter. The six-digit odometer shows 63k miles, approximately 5k of which were added under current ownership.

The mid-mounted 2.9L quad-cam V8 is equipped with four valves per cylinder and Bosch K-Jetronic fuel injection and was factory rated at 230 horsepower and 188 lb-ft of torque. A timing belt service was completed in September 2024, at which time the valves were adjusted and the water pump, camshaft seals, valve cover gaskets, spark plugs and wires, fuel pump, and heater core hoses were replaced.

Power is sent to the rear wheels through a five-speed manual transaxle and a limited-slip differential. The clutch, pressure plate, throw-out bearing, and CV axle boots were replaced in 2016.

Manufacturer’s literature, service records, a tool kit, and spare parts will accompany the car.

The Carfax report is free of accidents or other reported damage from its first entry in January 1992.
