for 70k TA with a LS motor I'd put a new windshield in and smile. Assuming that is all that's wrong with it. If its a 6spd it'd be a steal.
As long as the powertrain and body are in good shape the interior is relatively easy to find from people that track them and pull the interior pieces on forums. Also look at most TA's in good shape, still pulling over $10k sale value. Could be a good buy depending.
