Hello im a classic cadillac person i love the older caddys more than anything but im coming up on a nice settlement and would like some info on mileage with these new caddys. I have a 1992 cadillac deville with 208 xxx miles on it, and these old cars just need lugs and nuts tighten as maintenance, but theres this 06 sts v with 145k miles on it no modes just vanilla For $14k Is that bad?
