Wow. 17k miles on a 2007? Maybe you should drive it more!

I do agree with ard here. You're being bent over by the dealer (no offense, of course)...you need to take matters into YOUR court and TELL them what YOU WANT. Don't trust them, ever. Only time I'd trust them is if I had a warranty and nothing would cost me--in general terms.

Either find a good indy, or negotiate with the dealer on YOUR terms. Don't let them just tell you you need to pay $3000-$5000 and be fine with it.

GOOD LUCK!
