Comfort is big with Cadillac, so who else would offer massaging lumbar seats? Sure enough, this industry-first option is available on '99 d'Elegance and Concours models. All DeVilles get an electrochromic inside rearview mirror with compass added to the standard equipment list, in addition to an audible theft-deterrent system. There are three new exterior colors this year, and one different shade of leather inside. As if that weren't enough, side airbag deployment now communicates with the optional OnStar communications system, so the outside world will know when you've taken a broadside hit. Comforting, indeed. Look for a limited run of about 2,000 specially badged and optioned Golden Anniversary Edition DeVilles, painted White Diamond with gold trim, to celebrate the model's 50th anniversary.
