This is a great example of why I haven't been able to justify buying a used truck. This truck is 6 years old with 80,000 miles and I'm not sure how reliable the motor is in it, and they want $26k.
I can buy a brand new Ram 2500 Hemi for $31-32k or a CTD model for $36-37k. Paying the extra up front and getting a brand new and better (imo) truck with a full warranty seems smarter than saving the money in return for 6 years and 80,000 miles of use. It would probably take me 7 years to run up 80,000 miles, and at the end of that 7 years I'd basically own the used truck you're looking at now versus owning a 13 year old truck with 160,000 miles on it.
Just something to think about.
