Your car looks good in the photos, don't worry most have their niggles so it's just time, patience and some money of course. I think a weekend ride car that's well maintained shouldn't ruin your pocket once it's kept up to date. I had a 2.9 with a 3.6 conversion and it managed to get me hooked on the 40! The 2.9s are becoming quite rare so look after her, some had timing chain issues but good maintenance is the cue, you should be ok. The lattice wheels really suit the silver paint. See if she behaves reasonably for some time and then consider the cosmetic issues.
