When I look at GTS's for sale, I just move on when I see a nasty dent/scrape on the front fender or the left or right rear panel.
But I think this is largely a math problem. I'd be willing to pay X for the bike without that mishap. The scrape (if just cosmetic) will cost about Y to fix. So I can pay X-(Y +25%) for the bike. and yes, the pre purchase Inspection (PPI) will look for any other damage done.
So i'd like your rules of thumb for these repairs.
How much to fix a rear cowl dent and scratch where the bike fell over. (not a crash)?*
How much to replace the front Fender?*
*many of you don't like having to estimate costs when there are many variables and unknowns. Feel free to give a range or note that it is a WAG.
