No racing game has ever reached this level for PC.
I even miss the Test Center Server. That was pretty awesome. You could level up so fast, get to test some of the new parts, and all the other parts that you could just buy that weren't available on the regular servers.
I loved the fine detail that you could customize your car. I have to say my favorite car... was my '65 Citrus Flame Mustang. It was one of the gift cars that the game gave out. I think I got a Bel-Air for July 4th and a Ford Truck with the Christmas paint. I did like the trucks being added in, but i have to agree, the imports had no home in the spirit of the game.
I wish i could just install the game and magically connect to the server and race again. But its gone. ...But not forgotten.
