I'm completely new to Jags. Planning to trade in my 2014 Cadillac CTS 2.0T. I love my Cadi, but am looking to get something a bit larger with some more trunk space. These cars are pretty new, so not sure how many are even available with over 100k miles. That being said, what should I know when checking out the car? It has the diesel engine and the body and interior look very clean from the pictures I can see. My husband is very familiar with diesels and drives a 2012 F-250 Powerstroke with ~110k miles, and has had two diesels before that with much higher miles. So we're at least not completely blind in regards to basic engine functions. Anything I should be on the lookout for? Would all warranties be null because its >100k miles? Would appreciate any info at all. Thanks!
