From the pictures, it mostly just looks dirty... Once I replace the door card / window, all it really needs is a good detail.
From the seller's description, and what my friends have said, it runs pretty well. I'm looking into an M50/M52 swap though. I've got a friend who swaps them into E30's, said he could help me out wherever. In fact, just found a complete M50 for $1000!
Need a transmission though -- it's autotragic.
