Personally I want my sales car to portray that I'm serious and realistic. I want the car to be very late model and portray that I'm big time enough to have a dedicated sale vehicle, yet modest enough that the car isn't screaming money. I'd lease something reasonable, really whatever you can get for the lowest payment that you'd actually want to drive/be seen in. 24 mo lease at most. Full wrap or just signing doesn't matter, but you should definitely be unabashed about putting your name on the car. As for the car. I'd be looking for something like a prius, cruize, fuzion, jetta, you get the idea.
