If you have even a passing interest in cars, there’s little doubt you know a thing or two about Porsche, whether the topic centers around a classic name like 911 or the more mainstream Cayenne and Macan crossovers. Bugatti? Sure, most people know about the historic French builder of world-class, record-setting automobiles, though admittedly the EB110 we’re about to show you probably wouldn’t be the first to come to mind. Fewer are likely familiar with the likes of Vector Aeromotive, a tiny American company with history that dates back to the 1980s. And we’d wager that most have never even heard of the likes of Isdera and Cizeta.
Brush up on your history, (super wealthy car collecting) folks. RM Sotheby’s has an exciting array of cars coming up for auction during the Monterey Car Week festivities on California. Among all the expected Ferrari, Lamborghini and Shelby classics potential buyers can wade through, the so-called Turbollection collection features much rarer oddities.
