Buying a new car, got what I think is a decent deal at $49,000, and then dealer adds PA state tax ( $2940 ), new plate and registration costs ( about $100 ) AND thens want to add $500 documentation fee. I say no, and he says I can take care of the registration with the Department of Motor Vehicle myself, but it is a pain in the butt. Does this make sense? It is worth saving $500 to do it myself? Thanks Mark
