A battered, dirty, white Ford Taurus pulled into my view, belching fumes from its exhaust and rattling like a cheap kazoo. I needed to meet the client in half an hour and this car was my rental. Sure, I had reserved a vehicle online, but that car looked pristine, shiny and clean. What was I to do? Fortunately, the company realized their error and called another rental car service and secured a vehicle from them. As a business traveler, I really appreciate good customer service, and I was in awe that this company would go to such lengths to make up for such an error. Here are some of my picks for best rental car companies for business travelers.
