Points Awarded: 20
Destroy 100 cars by totaling them.
Another tricky one, you need to perform Totals as often as possible. The key thing to remember is to stockpile weapons so that you have enough ammo to pull off the total. You can then either finish the opponent off with the machine gun and let rip when prompted, or wait until they're almost wrecked and use a special.
For a successful Total, you can either use your character's special weapon, or an offensive combo (the Stampede and Buckshot work particularly well...)
