Buying a 240SX

I am about to buy 1990 240SX Coupe. The guy is selling it for $2000 obo. This is my first time buying a car from a private owner. I test drove thew car and it runs good. The only prob is the HUD does not work and the valve cover gasket needs to be replaced. What else should I look out for when purchasing a 240SX. Also how do I now if the car has a LSD. Thanks

take it to a mechanic and get them to look it over, they might charge you.
