I think it says something along the lines of "I'd rather have a car with body paneling made out of sheet metal, instead of this cheap-ass pressed artificial-resin-soaked scrapped-rags stuff for which there is no equivalent word in English, because everytime a piece of gravel bounces against the fender, it leaves a hole the size of a quarter, oh and by the way, I wish I had a real quarter, instead of those lousy, worthless, East German aluminum chips."
Or something like that.
