1991 Alfa Romeo SZ “Il Mostro 0511”

The Alfa Romeo SZ is a car for true enthusiasts without question

This example is number 511 of only 1,036 ever built, entirely original, exceptionally maintained, and accompanied by a fully documented history from its very first day. With just 54,000 kilometers, its condition is nothing short of remarkable. This is an Alfa that has not only been preserved with care, but unmistakably treated with respect throughout its life.

Known internally as ES-30, the SZ was a bold, forward-thinking project born from an intensive collaboration between the design departments of Alfa Romeo, Fiat and Zagato. While its lines were initially penned digitally — highly unusual for that era — final assembly was entrusted to Zagato's skilled craftsmen. The result? A car that looks more striking today than ever before. The angular design, the low-slung silhouette and the unmistakable six-headlamp front end give the SZ a presence that makes its identity immediately and unapologetically clear.

This particular example is finished in its original Rosso Alfa with a Grigio Scuro roof, paired with a beige interior. It is an authentic specification that reflects exactly what the designers intended. Once inside, the level of preservation becomes instantly apparent: the seats, the leather, the door panels, even the switchgear — nothing feels worn. On the contrary, the freshness of the interior aligns perfectly with the low mileage.

Under the hood lies Alfa Romeo's iconic 3.0-liter V6, a powerplant that delivers not only performance but also the unmistakable sound that aficionados immediately recognize. With 210 horsepower and a chassis derived from the Alfa 75 IMSA racer, the SZ drives in a way that actively invites you to engage. No electronic aids, no filters, no embellishment — just you, the road and a mechanical package that involves you in every movement.

What further elevates the value of this SZ is the complete original documentation that accompanies it. Manuals, brochures, parts books, factory literature — everything is present. For a model produced in such limited numbers, this level of completeness is exceptionally rare and deeply significant.

If you are looking for an Alfa Romeo SZ that is outstanding both cosmetically and mechanically, with full history and exceptionally low mileage, we warmly invite you to view this example in person.
