I went in to a subaru dealership looking at a 2.5i impreza and the price on the sticker was 17035 or something like that? Is that right or should I be able to get more off. I already signed the purchase agreement but can I opt out or try to negotiate more with the dearl to knock off 500 or more? thanks

if you know what your doing you can get the dealer to knock off another $2,000 off the price, you already signed the agreement so your screwed.

go tell them you found the same car for $16,000 and see what they say, I'll bet they match it

You signed - you are legally bound to the contract.....Negotiate BEFORE signing, not after.
