Walk away at a brisk pace and buy a rust free southern truck.
If you're in love with the plow & sander, offer hime $1,500 for them and tell him to sell the rust bucket to someone else.
I won't buy anything but brand new or close to new equipment from the northeast. Too much road salt, too much plowing, too much traffic. Trucks wear out faster up here.
I just bought a 9 yr old New Holland backhoe from S. California that looks better than my 2 yr old CASE backhoe. The reason is the climate.
My '92 IH came from central Florida and looks like a 5 yr old truck.
Look south my man. You'll be much happier. Trucks are cheaper down south, too.
Know any good web sites other than ebay for southern truck shopping?
