I'd still be pissed. Even though they fixed, SOME of the problems, you still paid 12k for a rusted s13. Did they ever fix your seat, or you still riding roller coaster, style?
I can kind of relate to your story, although I didn't spend nearly as much as you did. When I first got my s13, I didn't know jack about 240's, let alone swapping an sr. I blew my sohc, and picked up a redtop. Since it was my daily, I couldn't have it down for that long. Some guy on a local forum, pm'ed me, telling me that he could swap the motor for 750. Not too bad, I thought. Being the idiot that I am, I agreed. He had a turbo set-up, that was on a KA, so he asked me, if I wanted to buy a front mount, and dp. I said sure, why not, since it was pretty cheap. I got the car back, a week later, expecting the worse. Turns out, the dp, was homemade, and the welding was horrible. Front mount, wasn't in that good condition, either, but it does the job, and it was a big spearco. The swap, was actually pretty clean, and the car still runs fine, to this day. Will I ever take a chance like that again? Not in this lifetime. The hard part for me, is the fact that most of my friends, are into Honda's. So, when I need info, I look here, of google. Having friends, that are into the same cars as you, is a really big help, which I don't have. But, I do try to learn on my own, and I have, although I wish more of my friends, had 240's.
