Like those lead-spittin' heavy-metal classics, these big-bore vehicles handle the large jobs and look stylishly intimidating, whether they're working hard or just quietly holstered in the country club parking lot. Makers that got in early, like Ford , Jeep , and Toyota have struck gold. But there appears to be room for upstarts from Infiniti and Mercedes , as well as Lexus and Lincoln. We hope, for Cadillac 's sake, some SUV-market pie will be left to slice up for its '99 Escalade model. The customer desires in this class are silky power combined with grade-pulling tow muscle, rocky-road toughness, a smooth and quiet ride, loads of luxury features, and leather-lined comfort with space for at least seven passengers.
