Picked up a Trek Fuel 80 (2002) with a dented top tube, Deore 9sp.
(I paid $ for it so I'm a chump, must'v had a bad day)
Now that I have it I think the dent "looks bad" but for the XC riding this newbie will do I think it'll be fine.
Now that it's old, worn, dented and full of "character" I want to fix what's there and ride the heck out of it.
I can't afford fancy new stuff so I'll ride this into the ground for now.
I bought a rebuild kit for the rear Fox Float air sleeve, and will take the Manitou Black forks apart, clean and re-lube/oil everything. New chain and even a replacement Deore shifter/lever and Easton seatpost is on the way ($8 and $7, thanks Jenson).
At least I don't have to treat this bike nice!
Just thought I'd share. Pics to come.
