Destroy all Cars
Cars that are too old usually goes to the junk yard, but some people are still using it despite the danger that it could bring. You are a stuntman and you use those old cars in your stunts. In other words, you are paid to destroy those cars. The idea here is to get the right momentum, also adjust the height of the ramp to get the right percent of damage to the old cars. You can only get to the next level, once you reach that percent of destruction on the old cars. If you failed to reach that percent of destruction then you need to do it again.
