In Quick race mode, choose the 41st Street Raceway. Choose the Stanger 2000 and select "Race". When the race starts, go around the first small turn around the starting line and floor it around the longer curve. When you approach the smaller curve again, drive straight into the white tires sticking halfway out of the ground. When you hit them, your car will flip and fly through the air, hit the invisible wall in back, and land with a crash.
Set the realism to 100%, then choose the Stanger as your car and start a single player race in Peakview. When the race starts, drive into the pits to the left where the cars and trailers are parked. Drive to the right end until you hit the wall, then turn around and look down the aisle of cars. You should see the front end of a blue Ford minivan with people on top of it. Drive toward it as fast as you can, turn a bit to the right, then hit on its side. If done correctly, you will flip through the air and land on your wheels.
