Mike Jackson used to shovel horse manure for one dollar a stall. He wound up leading a company selling over half a million new and used cars and trucks a year.
In March, Jackson stepped aside from CEO of AutoNation, the position he held for 20 years. AutoNation is one of South Florida’s largest publicly traded companies -- worth almost $3.5 billion. And Florida is its most important market, with quarter of its revenues coming from auto dealers it owns here.
