When I first seen this topic, I thought the topic was on Mercury cars. If so, I'd say that you'd better hope some of the ones from Gran Turismo 2 will be in GT4. But since this is getting into the car company I've recently got into (Mercedes-Benz), I can tell you this based on the "E3 2004 Demo cars...304 CARS BEWARE!" topic, you'll see maybe 11 or 13 pages worth of cars. I can tell you the DTM racer (maybe), a Mercedes race car from 1992, a sportscar from 1989 made with Mercedes and Sauber, and even a car that didn't make it to GT2- the Mercedes-Benz CLK-GTR from 1998. I kind of wouldn't be surprised to see the CLK-GTR from Le Mans 1999 in the game, even though its aerodynamics were horrible, flying into the air and flipping out of control. In one way, better be thankful they were closed-top cars, because if they were open-tops, the drivers could have been injured or even dead.
