When the operator of Dadeland Dodge needed some political muscle to get a deal on 4.6 acres of taxpayer-owned property pushed through the Homestead City Council, he found a staunch ally in Jimmie L. Williams III. Williams, a bespectacled councilman and church pastor who sports trademark bow ties and - records suggest - may not live in the city he represents, became a fierce advocate of Jay Rivchin's proposal to build a Hyundai dealership on the site of a forlorn, long-shuttered bowling alley on U.S. 1. He worked tirelessly from the dais - and, it turns out, secretly behind the scenes - to ensure the public land sale went through without a hitch.
