I'm looking at some Sierra 2500 HD work trucks today, 2010 and 2012. They are in decent condition but with 140,000 miles and 200,000 miles. 6.0 motor, automatic. I haven't found any comparable trucks in my area to price them against, and the person is expecting me to make an offer. I understand the 6.0 motor is good, I need a second gas motor to tow with in the winter.
Could anyone that watches the market give me some idea on where to start with a price for these?
