Always ask how long its been there and ask a million questions. You want to know if its used and exactly what work was done and exactly when. During the negotiations when they come back scribbling on a peice of paper, BRING YOUR OWN BLACK THICK PERMANENT MARKER and start writing your own prices. Lowball them. But don't ever be rude, smile, be polite and firm. DON'T EVER ANSWER ANY QUESTION IF IT SEEMS LIKE THEY ARE TRYING TO SET YOU UP OR MANIPULATE YOU. JUST TELL THEM SORRY I DON'T WANT TO ANSWER THAT. Most used cars will be marked up $4000. Start your negotiation 3500 below the asking price. DON'T and I mean DON'T tell them how much you want to spend per month. They will hold you to that. Just tell them you want a good deal. It's about $20 per 1000 for your monthly payment. so a12000 dollar car is about 240 a month. Be careful of any questions you answer - THEY USUALLY ASK YOU A QUESTION TO LEAD YOU UP TO SOMETHING. Don't threaten to leave if you don't get your deal just be patient, firm and smile. Any questions just hit me up.
