About the Alfa Romeo SZ
The Alfa Romeo SZ was developed in collaboration with Zagato and based on the Alfa Romeo 75 platform. Its radical wedge-shaped bodywork, designed by Centro Stile Zagato and refined by Fiat's Centro Stile, divided opinion when launched but has since become iconic. The composite body panels were hand-laid over a steel spaceframe, keeping weight down to around 1,260kg.
Power came from a 3.0-litre Busso V6 engine producing 210bhp, enabling 0-60mph in around 7 seconds and a top speed of 152mph. The SZ featured advanced aerodynamics, a limited-slip differential, and suspension tuned by Giorgio Pianta. All examples were left-hand drive and finished in red, though a handful received special colours. The roadster RZ variant followed in 1992-1994 with just 278 built.
What Affects the Price of a Used Alfa Romeo SZ
Condition is paramount with the SZ, as restoration costs can be substantial. Original, unmodified examples command significant premiums over cars with non-standard parts or paintwork. Mileage plays a crucial role, with sub-30,000-mile examples fetching top prices, whilst cars over 70,000 miles typically sit at the lower end of the market.
Service history is critical, particularly evidence of timing belt changes and V6 engine maintenance. The composite bodywork can suffer from delamination and cracking, which is expensive to repair properly. Provenance matters greatly, with documented history, original handbooks, and traceable ownership adding value. UK-registered cars may be slightly more accessible than recent imports, though all SZs remain rare.
Tips for Buying a Used Alfa Romeo SZ
Inspect the composite bodywork thoroughly for stress cracks, particularly around the wheel arches and bumper mountings. Check for proper panel fit and any signs of accident damage or poor repairs. The bodywork is difficult and costly to repair correctly, so walk away from anything dubious.
Examine the V6 engine for oil leaks, especially from the cam cover gaskets and sump. Ensure the timing belt has been changed according to schedule (every 36,000 miles or four years). Listen for any unusual noises from the engine or transmission. The limited-slip differential should engage smoothly without clunking.
Verify all electrics function correctly, including the pop-up headlights, electric windows, and instruments. Check the interior for wear to the sports seats and dashboard. Join an Alfa Romeo owners' club before buying to access specialist knowledge, and consider having any potential purchase inspected by a marque specialist. Budget for maintenance costs, as parts can be expensive and specialist knowledge is often required.
