There's an interesting 2005 FG140 on the Ritchie Bros site up for auction in Alberta in September:
It's stated as having "frame damage". It's hard to tell exactly what is going on from the photo, but it seems the frame mounted crane might have tweaked things a bit? Or maybe it was just overloaded.
Probably a real deal if anybody wants to delve into frame repair. (I sure don't!)
There have been a lot of FGs and FG140s coming up on Ritchie Bros in both the US and Canada. There are some good deals if you can act fast and don't mind buying something sight-unseen.
