The finance manager tried to get me to finance it, and buy the extra's as they make their cut from that, so I'm surprised your friends experience on that end went well, unless she did purchase the extra's.
I asked if they could throw in the rims, he said they couldn't. It was only when I contemplated about the rust and paint protection was when I was told if I bought the module, they'll throw in the PP.
I had cash, they knew but tried to get me to finance at 4.5%. Then there's the processing fee, $66. Salesman said it will be great for my credit. I said my credit is A+ already. I cancelled and paid cash. He said that was silly. Silly is paying more than what my money would have made in the bank.
Next car, a low-K used one as my Toyota, had 4K on it when I got it.
