Cadillac considers the STS the best luxury sedan they’ve ever made-- and they’re not wrong. Traditional Caddy buyers will be pleased with their new whip. But any Cadillac exec that thinks the STS’ has enough ride, handling or comfort to lure buyers out of their bombing Bimmers, massive Mercs and liquid Lexi did too many mind-altering substances in the 70’s. More worryingly, the STS lacks sufficient sizzle to delight the Brothers. If Caddy wants to maintain its current momentum, they need to stop chasing Eurostyle and, like Chrysler did with their gangsta-rrific 300C, get down with their bad selves.
