A friend is offering to sell me his 2007 Dodge Cummins 4X4 quad cab for what the dealer is offering him in trade. It has an auto trans and the truck has always been properly serviced. The truck looks cosmetically excellent. Truck has 212,000 miles on it. Here's the problem: He was towing and got a sudden power reduction. He has it checked out and the shop says some injectors are unequal and the computer may have issues. The check engine light is on but the truck still drives. Should I buy it for $6,500 or forget about it? I currently have a gen 1 Cummins (1989) which is only regular cab and is really ugly. Should I do this deal? Thanks for your opinions!
