Comedian Adam Carolla is a very unique car collector, especially when compared to some of his peers. Those other well-known "Hollywood" automotive enthusiasts, who include Jay Leno and Jerry Seinfeld, are often spotted on public roads driving priceless cars from their private collections. But not Carolla.Two years ago, when we visited Carolla's Southern California home , we were awestruck by his pristine Datsun Camel GT pace car, Bob Sharp Racing IMSA 300ZX and his custom Datsun Roadster 1600. In another corner, we took cloth covers off a gorgeous 1967 Lamborghini 400 GT 2 +2 and a Lamborghini Miura.While most of us would jump at the opportunity to tool around in any one of those classics, Carolla recently told eBay Motors that he has no interest in mimicking fellow stars like Leno. He doesn't relish the attention expensive machinery garners, and there is always the chance something is going to break. Even worse, the accomplished vintage racer said that the streets of Los Angeles are chock full of cops - that takes all of the fun out of nailing an apex at speed.So Carolla's collection will remain, in perfect condition, stored for his own admiration. His daily commute, grocery errands and trips to the studio will be run in standard production vehicles - they draw fewer eyes. Don't ask him to change, either, or he'll give you something to think about: "Does anyone ask a stamp collector if he uses his stamps to mail in his gas bill?"
