Richardson's may be the oldest business operating on Grosse Ile's main street. This tiny, full-service gas station will remind you of the early days of automobiles -- and its customer attention is a throwback to those days. You don't pump your own fuel here -- an attendant services your car from one of four pumps, one designated just for diesel. Although the service is old-fashioned, the technology is top-notch: the station can handle all major and minor mechanical auto repairs, offers towing and performs snowplowing for commercial and residential properties.
