Hey everybody, once again, your expertise is requested. I found this truck and need your opinion. Here are the specs. 1997 GMC W4 4500 14' box medium duty truck 3.9L 4 cyl diesel 109 in wheel base Brand new engine new turbo new transmission 5000 miles ago new (4) rear tires New brakes No A/C Exterior cosmetics are good. No major repairs needed. Interior, Dash board clips and passenger windor handle needed. Well, there are all of the specs. The guy was asking $7500. What do you all think. What is this truck worth? Is that a good deal? Please let me know. Also, what would it cost to put A/C in it?
