The Simpsons: Hit & Run Tips

Fix cars for free
If one of your cars blows up you can fix it for free. What you do is after your car blows up is to go look for a wrench (the wrench that fixes the damage on your cars), but you must run there because if you get into another car it will repair that car instead. Once you get the wrench, your blown up car should be repaired. No extra cost.
