I'm 100% in agreement with Roger & Nick on this. When I first read: "'98 with 30k" I said to myself, "Wow". But when I saw 8k as the asking price, I said "Whoa."
After 16 years (17 with the new '15's out) the whole low-mileage thing might be worth maybe 1k, but as Roger said, this is a $4,000- $4,800 truck depending on the condition of paint, interior, etc.
Take Roger's advice, and offer $4,500 if the cosmetics are nice. :smileup:
