In a world that has more supercars and sports cars than you can keep track of, it’s pretty easy for those that don’t go mainstream to get lost. It’s sad when you think about it. Over the years, there have been some interesting concept and production cars that never got the attention they deserved. Take the Tushek Renovatio T500, for instance. Have you ever heard of it? I’m guessing you probably haven’t, but it was a remarkably beautiful car with distinct styling that should have made it a favorite among collectors.
