New car: Overheating Issues

[supersupra986]

Hey! i'm new to the whole forum stuff but i was wondering if you could help me out. i'm planning on buying an 1986.5 supra 7M-GE it looks in good shape the guy says it runs great and shifts great. but he said and i quote "it needs a little bit of work, the thermostat needs to be replaced cuz it overheated and i've had it parked since" is it possible that it overheated from the thermostat? also is there anything i should ask him or look for when i go pick it up? was also thinking that if it is the thermostat would i be able to bypass (remove) it temporarily to drive it home with no damage to the engine? and if possible could you send me a picture of the location of the thermostat and direction on how to remove it? Thanks!
