Wow, I'm exactly the opposite. I won't ever buy a car without driving it first.
Oh well, what do I know? I must be a chump.
Well when I test drive, the salesmen call it a "chimp drive"
My Dad helped me buy my first car, he was the best negotiator I've ever seen.
He started at invoice and went down from there. It was before the internet and not easy to get the invoice price of a car. He knew the invoice price down to the penny. The salesmen made fun of his price, laughed at him, had trouble catching his breath, said things like I don't know where you got that at, but we paid alot more than that. Lot of silence, I was about to cave, when he said "Let's go talk to my sales manager".
The sales manager showed me the invoice and it was to the penny what my Dad had been saying, that caused the caused the saleman to have the laughing fit outside.
Dad said you have an end of year kickback from Ford of $750 for this vehicle. The salesmanager started laughing and said "YOU'VE GOT TO BE KIDDING!!" My Dad told him that $350 incentive from Ford Finance for the loan, the salemanager said he wouldn't be able to give me the special financing, which was the main reason I was willing to buy. My Dad said you get a $600 flooring allowance, and this guy caved.
I got that car (Bronco II) for almost 2 grand under invoice, like 4 grand under the sticker price. My Dad never raised his voice, never asked for anything, just told them what the invoice price was and the kickbacks they got. Oh yeah I also kept the special Ford financing.
The one thing my Dad told me was if I needed to test drive, go to another dealer and test drive it (which I did). He said when we went there it was to buy. No test drive, no looking it over (I did this the day before) - nothing. On that car he didn't need to negotiate, these guys caved.
My brother in law used to sell Toyotas and Chevys, and he has told me that all the salesmen were really intimidated when someone came in to buy and barely looked at the car and wouldn't test drive it. They freaked.
Unfortunely, I didn't get the negiotating gene. That experience really taught me alot. Mainly, just how full of bs some of these guys are.
