re: car buying question

It seems like you have everything in your court. I see two options here, get GM dealer involved and get other Nissan dealers involved. I've heard that as long as you let the dealer know you are shopping around, it's fair game. You have plenty of time to call other dealers and lay it on the line about what offer you currently have, and what you want.

I bought a car last week and the dealer didn't get motivated until I brought a competitor into the mix. They even matched discounts I could get through my employer with the other manufacturer.

BTW - I use this for up to date REAL car prices
