10: Mark Martin
Another popular name in NASCAR for two decades was Mark Martin, who had the most wins in the Xfinity Series with an impressive 49. Martin was always a major proponent of driver health and fitness, which enabled him to drive well into his fifties. Martin also opened up four car dealerships in his hometown of Batesville, Arkansas. Toward the end of his career, the driver was focused on mentoring the next generation of drivers.

More recently, Martin and his wife left Arkansas and moved to Montana, where he enjoys spending the summers. There have been a few instances where Martin will pop up on NASCAR TV, but for the most part, he is enjoying the quietness of retirement. Martin was one of those drivers who never made it to a superstar level but still managed to do well for himself.
