That's not a great price around here. I'd not pay more than $20k for a package like that.
Breaking the plastic grill is nothing, it's so easy to do with a grapple or just even driving through a field and a branch hits it. Wouldn' think twice about it, if everything else looks like it was maintained.
Regarding the L/MX, I am in the same boat. Just a few more payments left on the L so I desire to keep it and buy a cabbed MX/M.
I know this is a Kubota site, but if my options were between your package, and a new TYM 474 for roughly the same money, I'd be dragging home a TYM/RK tractor.
