hey gents I have a few questions about a 2007 Dodge 6.7 liter. I have an opportunity to buy one for 23k with only 19 thousand miles on it it's a6 speed standard 4x4. I've done some research and found that year was the first yearthat it came out and also had a lot of issues with the DPF. so my first question would be is it worth the buy and 2 would a DPF delete help the problems that that 6.7 liter has? any additional information would help as well
