So I'm talkin to this guy that I found through DSM Trader who is willing to sell me his 1996 TSi AWD as a trade for my 1999 Eclipse RS

The TSi has 64,000 miles (whether this is original or on a rebuilt motor is unclear at this point) Also, the TSi is unpainted and just primered black. He says he needs a new flex section for the DP but that it runs. It supposedly runs kind of rich because he used to have an 18g turbo on it but now it is back to stock T-25.
Here is his DSM Trader ad: http://www.gopartstrader.com/cgi-bin/suite/classifieds/classifieds.cgi?request=detail&id=224606&category_id=106&sub_id=1040&variable_file=autos.variables&group=1&set=2&position=33&total_count=552&website=default&prev_action=display_sub_list&session=4252e4e335fe2327

My car has 132,000 miles on it, but it's been meticulously maintained by me. I got it w/ 100k and the exterior/interior are in almost MINT condition.

CLIFFNOTES: He wants my car plus $500 for his car. Good deal or not?
