It's very difficult to give an average price on a car since there is so much variation and there are so many nuances to each car.
What I can say is that, on average, we save buyers over $3000 off the sticker price of the car. The range of savings is $-6101 to $16,205 (for a car that was very difficult to find and one that the dealer clearly wanted to move, respectively).
I can't knowledgeably comment on pricing by location right now, but we'll be releasing some cool data around that in the near future.
