Perhaps you could be more specific as to how you consider the experience "broken".

Having bought both new and used cars over the years, I wouldn't buy a car without checking it over and taking it for a test drive. Due to that physical aspect, I'm not sure what you wish to "fix".

Assuming that you dislike car dealers and pushy salespeople, you can buy used cars privately through any one of several websites and use brokers who have access to considerable discounts if you want to buy new.
