I have the same problem, and also the opposite problem. I used to get them coming up to me when I was in my GN. The problem was I had a very original paint job, so I couldn't fool around close to home. I didn't want to be noticed by the local boys in blue. Now I have the drive train in a plain Jane station wagon, and I can't seem to find them. I do occasionaly waste a few of them on the highway, but most won't even play. They don't want to waste their time with a wagon. I've tried to get Porsches, and even a Ferrari to play, but they figured it was a waste of time. Lucky for them. I would've sent them into the breakdown lane crying because they spent so much for a tird. Mustang owners for some reason, are always up for a race, but they as have been mentioned, are always going the other way, or go by when I am in my slow wagon, or my truck. I usually just go to the track to play now. The problem is, everyone there seems to know the car, and the announcer tells everyone what is under the hood, and what I get for times before I even make my first run, so there is no surprise/shame.
