hi everyone,
my buddy is selling his 1999 F-250 superduty for 17k. the truck is 4x4 Turbo diesel v8 with 116,000 miles on it. It has lots of extras (custom gauges, clearance lights, bed-liner ect. and is in GREAT condition) I have been looking on the internet for similar trucks but haven't found many. I was wondering if this is a good deal? kbb.com said that it was right on the money but i just want to make sure before i make a big purchase. Any help would be great!
