the most wins (15). In 1991, Harry Gant became the oldest winner at . It was Gant's fourth win in a row, earning him the nickname Mr. September. Ownership of the track was a joint venture of brothers Jim and Bill France Jr., and H. Clay Earles, the majority owner, along with daughters Dorothy Campbell and Mary Weatherford, and Dorothy Campbell's children, Sarah Fain and Clay Campbell. In 2004, the track was sold exclusively to the France family for over $200 million as a result of an estate sale following the death of Weatherford. International Speedway Corporation (ISC) became owner of the track. Plans had existed to add an additional 20,000 seats along the backstretch, boosting capacity to over 85,000 seats. In 2005–2006 the Norfolk Southern Railway behind the track was moved 200 feet to make way for the added seats, but nothing more has been officially mentioned regarding this by track management since the sale of the track to ISC. From 1982 until 1994, and again in 2006, the speedway hosted Busch Series events. This occurred first with 200- and 150-lap features (200 laps for the two races with Whelen Modifieds, 150 laps with the September Winston/Nextel Cup race), then 300 laps from 1992 until 1994 as part of a Late Model/Busch Series doubleheader, and 250 laps in the one-off in 2006. The venue was dropped from the Busch Series schedule for 2007 and a race at Circuit Gilles Villeneuve in Montreal was run on the open date. Currently, Martinsville hosts two NASCAR Cup Series races — the Blue-Emu Maximum Pain Relief 500 in late March or early April and the Xfinity 500 (race nine in the NASCAR playoffs) in late October or early November — along with the NASCAR Camping World Truck Series, NASCAR Whelen Modified Tour which is held on Labor Day weekend under the lights, and late model races. NASCAR Xfinity Series also races same weekend as cup series playoff race (which is next to last race) in Xfinity series. In 2012, Martinsville Track President Clay Campbell, Langley Speedway's owner Bill Mullis, and then South Boston Speedway's General Manager Cathy Rice formed the Virginia Triple Crown.
