If you take it in with this laundry list and they can prove it existed before you bought it, they will not cover the repairs. "Pre-existing conditions" are not covered in service contracts.
My daily is a rotation of Tudors and Omegas, particularly my Seamaster 300M. The shiny safe queens (Actually, winder queens) are the Moonwatch, The Sub, and a TAG. I have one Breitling to remind me to never buy another.
I get quite the reaction from some shooters when they see the cosmetic condition of my Wilson that I carry....It's a tool, not a safe queen.
The Swiss watches on my wrist, however....guilty.
Don't know about the Chevy, but RAM won't put a diesel in a Power Wagon because the expanded cooling system won't allow them to put the winch on the front end. Larger oil cooler, trans cooler, radiator.
I had two Ram/Cummins trucks. Never had an issue with either. It's what I'm leaning on going back to, as I stare at the check engine light on my dashboard AGAIN for this wonderful Chevy. I like the looks of this Chevy....But their technology really sucks.
