ok guys and gals.... i was driving around and i saw a truck that i really like. They want 19,000 for it and the guy offered me way too much for the trade on my truck....(He really liked it and said he was going to buy it) I have a 2001 Yukon with 100,000 miles on it with a stereo that will blow doors off, brushguards, roof racks, and loud exhausts.... I think i can get 13,000 out of it. The truck i want is a 2004 Chevy 2500HD Duramax Diesel, With Banks Power Pack and 140,000 miles. The guy has changed the wheels on it, put a bedliner in it, changed exhauts, and it looks to have been taken very good care of... I want to drive it today, and see how I like it.....I know i will be amazed by the power difference in pulling trailers, and just driving without....Another good thing is the gas mileage is better than my yukon, and diesel prices are dropping (2.52) by my house. My dad is saying diesels are too expensive to work on, but with only 140,000 on a diesel, it will run til 300,000-500,000 if taken good care of.....What do yall think, should i go back and look at it, or stay away. I think i could talk him down to 17,500 - 18,000. What do yall think my yukon is worth also? 13,000?
