I purchased my 2014 CTS-V wagon new in 2014. This is my only car. I have a second set of OEM wheels with my winter tires on it. Other than the goofy front end alignment issue (if you don't know these were made without cam bolts which is a big mistake in my mind) the car is truly bullet proof. I don't know who has the most mileage on theirs but since mine is a '14 I am probably not in first place. Mine just turned 185k last week and I could not be happier. Original plan was to keep it to 250k but I will probably go longer.
