1970 chevy 3/4 thinking about buying
 

This truck is making me crazy I wanna buy it but I dont know much about these things and dont know what to check for as far as getting a money pit. Any advice? I have not seen it in person yet, just been talking to the guy on the phone and looking at pics. It runs, Registered, needs seat and stearing wheel and brakes, inside of bed is damaged a little. I can pick it up for $800

Thanks for the help if you know somethin

70 chev
 

These were very prone to rust even rusting thru the door skins so be alert to that.
