Something every girl wishes her man would be driving. The most bad ass diesel engine money can buy especially the 5.9 12 valve which is way better than a power stroke or duramax which usually has 8 cylinders while the inline 6 only has 6 cylinders because the only V that should be in your truck should be riding shotgun. The only reason i would not buy a cummins is if it was a 53 block or you see a typical teenager is selling in and the only upgrades are a 5 inch straight pipe to a 8 inch tip and a 6 inch lift with a edge computer system that makes it roll coal which usually means there is something wrong with it and the dip shit wanna be country boy wasted his dads money and a HELL of an engine.
damn Henry do u hear that hummin?

yeah that must be a cummins.

(5 seconds later) yep there she is smokeing out a 6 ohh
