I have a decent read on the value. I know that cosmetic repairs only decrease the value. All the dings and dents were before I owned her. IMHO, her first 10 years prior to me, were rougher than her last 30 combined with me. Its about her appeal to me. I just see all these guitars all shined up and flawless (my Strat is like that). Its just me. I'll get over the fact she will never be flawless.
I had given serious thought on trading her for a Gibson Les Paul Std, Trad or Custom. My wife is totally against it. She told me to go play it a while and think about it. I went and played all my guitars. She was right. The Mustang plays better and easier than all my others. Hell, my Bradley even beat my Strat for ease of play. And my Strat is very easy on the fingers. She just need some TLC. I am scraping the funds together to get her a fret leveling (first in 40 years) and full setup. A good non-abrasive wax job should help the finish.
