Only my opinion, but I would steer clear of Bill Buck Chevrolet in Venice. Have heard some negative experiences concerning that dealership.
One in particular, he sold a Vette that supposedly had a "clean" Carfax report, car was put up on a lift after the purchase, and there had been MAJOR damage to the car. Maybe the dealer didn't know about it, I don't know cause I wasn't there, just relaying what I've been told.
On another note, a friend of mine just preordered an 07' Z06 from Ed Morse and had very good service. Go figure......
