Stop in for a cup of coffee

Mike, is it super quiet when you are driving? Buicks I have driven recently are quieter than Cadillacs, spoiled me for other new cars.
It is very quiet. I was impressed. They use triple door weatherstrip I read somewhere. This one is the Premium II so it has every option except a moon roof (which is ok in my book) It does everything but wipe your butt. (as my Dad used to say) {RIP}
