re: Haggling over a new car saved me over $1300

You probably did cave to early I imagine that if you have some research on what that car fetches at auction or looked at the trade in value of that car(the one your buying) and started your negotiations from there you could have got another 500-750 off.

When I bought my last car I went into it strategy real hard read like 20 internet articles on it and really researched what I wanted. Don't have buyers remorse because to extract that extra amount out of them is just not worth it IMO. They make it to hard and long of a process. Plus you feel like a jackass arguing over 5% of the value of the car.
