I owned 965/2000 January to July last year. My plans were for a full drag build, but I lost interest and never got started, 145/2k was bought at the same time, and it was the more promising one to build up between the two.
965 has changed hands alot over the last several years. From what I can tell on the vehicle history report it has not been driven since at least 2001. From what I could tell it was very free of rust, there had been bondo work done in the quarter panel areas, but looking inside the trunk area where that is, it didn't appear to be anything too deep, just poor body work.
Having changed hands so many times, the right owner needs to come along and snatch it up, strip it to the shell and do a full frame-off (so to speak) restoration IMO, otherwise there is really no hope. I still have the AutoCheck vehicle history report (if the current owner would like a copy, I'd be glad to e-mail it), and it is clean, no accidents reported or anything of that nature.
What whomever does purchase it does need to realize, as with even the cleanest of Galant shells, these things are approaching 20-years old, and to get it back on the road (and be reliable), will be neither cheap, nor easy.
