Dealers generally hate sites like CarWoo and TrueCar:

Search that forum for lots of lovely language from the dealers about those two. TrueCar is particularly despised.

There is some positive feedback from dealers about CarWoo though, more so than TrueCar, so perhaps they figured out a thing or two better.

I think it's only the small-time dealers that hate carwoo. Have a look at the comment by Scott Salzman on that forum, which fits with my own experience. I bought my car through carcostcanada.com, and my local dealer couldn't even match the no-haggle quote I got through the site (their best offer was 1k more).

The dealer I went with was a high-volume dealership in the city. Not only was their price low, but they also were very friendly and helpful. It makes sense to use sites such as this - it's a huge time saving for both the customer and the dealer.
