DORAL, Fla. — Pablo Sandoval pulled up to a custom car shop here on a recent Friday afternoon hoping to do some business. He wanted to trade in the Porsche Panamera he was driving, order new sets of rims for his two Range Rovers, pick up the gray one that was being worked on and discuss the next car he would buy — a 2016 Rolls-Royce Ghost.
Sandoval strolled inside and, seeing that no one was behind the front desk, leaned on the counter and playfully smacked the bell several times, announcing his arrival. The owner, a Miami native named Alex Vega, suddenly emerged, smiling, with a phone pinned to his ear.
