Alfa Romeo SZ: rare coupé, engine and what to know when buying
The Alfa Romeo SZ is a two-door coupé designed and built by Zagato, released in a run of around a thousand units between 1989 and 1991. It's an extremely rare collector's car that enthusiasts are always on the lookout for. We delve into its features, engine, and what to check before buying.
SZ in brief
The SZ stands for 'Sprint Zagato' – an Alfa Romeo coupé with a body designed by the Italian studio Zagato. Due to its distinctive, angular shape, it's nicknamed 'Il Mostro' (the monster). The car is based on the technology of the Alfa Romeo 75.
The body panels are made of plastic over a steel frame. The car was produced in very limited numbers, so they rarely appear on the used market, and the price is collector-level.
What to know when choosing
Only one version was produced, so the choice depends on the specific car's condition, history, and originality. Some cars have lower mileage and are preserved in collections, while others were used daily.
Pay attention to the documents and proof of origin. Due to the small production run, it's crucial that the car is a genuine SZ and not a conversion based on another model.
Engine and gearbox
The SZ has a 3.0-litre V6 petrol engine with around 210 hp. It's the same engine used in other Alfa Romeo models of the time.
The gearbox is a manual five-speed, with rear-wheel drive. There was no automatic option.
What to check when buying a used SZ
Check the plastic body panels for dents or poor repairs and the steel frame and underbody for rust. Body parts are very hard to find, so repairing damage can be expensive.
Check the condition of the V6 engine, the timing belt replacement history, the cooling system, and for any oil leaks. Test the front suspension and gearbox as well as the rear suspension.
Before buying, consult a specialist in classic Alfa Romeos and check the documentation. Finding parts can take time, and some are simply unavailable.
