Thinking of buying a 5.7 Dodge Magnum

Sorry if this is the wrong thread for this. I wanted to know if there are any critical problems with these boats before I make an effort to get one. I see a ton that are 130k+ miles but my Dad's 03 Ram is almost at 200k and is only just now the transmission(3/4 ton Cummins towing weekly) is starting to have weak shifts.

I've heard the 5.7 develops problems in its old age.

I'm asking you guys because i trust FABO much better then a salesman.
