Buying a 2012 Mazda Mazda3, and saving $500 off of MSRP.
This was the only Mazda Dealer willing to actually negotiate with me, and give an idea of how much they were willing to come down. I was only able to get a few hundred dollars off the MRSP, but that was the best I could get wtih a brand new 2012 SkyActiv model. I ended up right within the range the Car Cost report suggested I could get the car for.
