Buying a "driven" D versus a "stored" D?

[heskin@xxxx]

Hello All,

What types of problems should I look for when considering buying an 
'81 Delorean with 3,700 original miles? I know about the throttle 
shield update, but how do I test the fuel tank, seals, and other 
updates? Would frame rust be easily spotted if put up on a lift? 
What parts should I plan on replacing right away, assuming the car
has been garaged for the duration (besides the obvious things like 
tires and fluids)?

Thanks in advance.
