Buying a 2012 Ram 1500, and saving $5000 off of MSRP.
Dealer was very helpful in trying to locate vehicle with exact specs and options that I wanted and offered a great discount with no haggling. The dealer gave me a price that he told me was $400 over invoice and I new it was accurate since I had used the CarCostCanada website. Saved a total of nearly $13200 off a 2012 Ram Laramie including the $8750 incentives from Chrysler.
Buying a 2012 Dodge Grand Caravan, and saving $7000 off of MSRP.
I chose the vehicle and dealer because they 2012 were priced at what the 2011's should have been priced at. I used Car Cost to ensure I was in fact getting, what I thought to be, a good deal.
I would always suggest doing a great deal of research before you buy and let the dealer know that you have done this so they are more likely to accept your requests when you don't want to pay for things like Satelite radio or other so called perks.
