Note to BMW dealers: That grille filling up your rearview mirror may not carry a Lexus badge after all. Shocker of shockers, if you look closely you will see a crest, a Cadillac crest, followed by the unmistakably angled snout of the 2008 Cadillac CTS. Redesigned on the inside, touched up on the outside and strategically improved in its road manners, the CTS is joining the luxury sedan party – and this time, it’s not wearing blue hair, bifocals or a clown nose.
