Actually, it may have ben closer to $15,000 since I had to pay a $499 "documentation fee". It was $16,8xx out the door (after taxes and tag/title fees). I used truecar.com, and ended up getting an even better deal than what was on the truecar "certificate." There was a $1000 mazda "incentive" discount that helped (since I was not financing it). Keep in mind it was the sport model with no options.
I also used truecar for my 2, but since I opted for the 0% financing I did not get any "incentive" discounts. It ended up being about $15300 out the door for the 5MT touring, but it came to me with window tint, armrest, cargo net, and wheel locks for free.
I definately recommed using truecar for buying new cars, but unfortunately there just aren't too many "truecar dealers" around.
