If you do buy it, make sure you explain that when backing up, the car must come to a complete STOP before moving gear selector to drive. This will help save your new trans. Your other issue is going to be paying for premium gas. Premium gas is a must if you are going to thrash on it or you will end up destroying a front piston. As he is young and always broke, he may not want to use the expensive stuff. Good luck, read the FAQ and search when it comes to maintenance.
