I had a huge dissapointment when I tried it out. I was just drivin, and drivin not a worry in the world, till I went back to my garage. I was thinkin the whole time that I wasn't putting mileage on the car, thought I found a way around the whole gaining mileage online thing. For me, I'm not so worried about the mileage, as I'm worried about the stupid engine/chassis rebuild. There seems to be no way around the gaining mileage, unless you go online, and never actually enter a race. This does however, still make it so you need a chassis rebuild.
