I’ve always found the SMART car to be quite impractical. Its extremely small, has almost no boot space and very claustrophobic if you get stuck in it on a Michigan freeway. But, while in Miami, I spotted this really cool custom at Coco Walk. I have to say, I like it very much. The open-top approach absolutely works for it. But only in Miami, where the weather is awesome year round – would this be practical.
