92 Civic trade for 98ti?

[Airric13]

I have a 1992 Honda Civic with all the details at this website: http://www.cardomain.com/ride/2584850 I am tired of a stiff suspension and want something mroe comfortable to drive to and from school and work in. I have an offer right now for a 1998 318ti, black with black leather interior, 17" wheels (don't know what kind), 115k miles, automatic (not ideal, i Know). The car recently had the window regulators replaced and the owner is only the second owner of the car. Bad news, headliner is falling down, I have replaced them before its not a big deal. The catalytic converter is clogged (he had the code read at a BMW dealer). BMW cats are WAY expensive, but it's just exhaust work. I could it cut out and a new one welded in at any muffler shop or with buddies who have a welder. My car has rust in the rear quarters, flat balck passenger door and driver fender, and some fading paint. But it runs neck in neck with an S2000 on the highway while getting 30-36mpg. Mine also needs a new header because it has rusted through just before the cat. The trade would be straight up, no extra cash on either side. What do you guys think?
