Jeremy - I think you've taken that the wrong way. Wayne isn't saying that he judges people on what type of car they drive, rather the condition in which someone keeps their car may be an indication of the attention to detail or general standards that the individual has.
It could be a 20 year old Hyundai, but if it's clean and not filled with junk etc. then that person is probably more conciencious than some one in a brand new Lexus filled with week old sandwiches, newspapers and bubblegum wrappers.

There may be exceptions I suppose...
