I went to the Crazy Ray's a Hawkins Point Tuesday and there were about 15 MBs. They had 3 450SLC, 1 450SL, a host of W126s, and a few W201s and W124s. Just a couple W123s. Just inside the gate they had 2 of the SLC and 4 W126s - right there! The first W126 on the end of the line was a 500SEL euro, the bumpers from which I own now.
The risk with Crazy Ray's are that they move their inventory very quickly. I tell you it was there Tuesday and it could have been crushed Wednesday - I make no promises.
Another risk is that they will nickle and dime you for every little part, for instance, you want a seat, that will cost you $X, but motors with it cost extra. It adds up very quickly. I have been to all 4 of their locations multiple times and have gotten the best pricing breaks at the Jessup locations. They even have a sign up that says something to the end that if you are nice you get a better price.
