do you have a list of dealer reviews

I don't think they do. They don't want dealers to quit advertising with them, especially the bad ones. Had vehicle I like which would have to be delivered to my city from 1,000 miles away. Decided not to when the dealer - Strong VW in Utah - on YELP had about 90% bad reviews; I read 10 pages of complaints and quit. Very deceptive place and hated by many buyers. It would be refreshing if they had some kind of tag for the places with more positive reviews than negative; at least it would be a start. Do your homework on YELP and other sources before you buy, just don't think CarGurus cares about who advertises on them.
