I have a '05 Dodge Cummins. While the body and interior is lacking in quality in some places, the engine runs great. So far, no issues with the 48RE trans, other than the parking pawl won't engage anymore.

But when I get in it, I don't have bells and whistles going off if I don't buckle the seat belt. No Sirius radio, no backup alarm, or camera tat takes the place of mirrors. Mine has no rust, so I'm putting money into it to keep it maintenance updated. I have no intent on buying anything new.
