I wouldnt trust them, looked at a few cars there out of curiosity... had one Civic being fakely sold as an Si when it wasnt, I think the dude makes his big bucks off of making cars look all sweet and badass...
He told me that that Civic Si would kick my Camaro SS's ass, even though it was 100% stock! Of course, when I pointed out that was the car I drove there, and that I'd race him right now, he bailed. Yes, and this was the owner I talked to :P Soon as I heard that I just laughed and left...
