David Alan Marcis (born March 1, 1941) is an American former professional stock car racing driver on the NASCAR Winston Cup circuit whose career spanned five decades. Marcis won five times over this tenure, twice at Richmond, including his final win in 1982, and collected 94 top-fives and 222 top-tens. His best championship results were second in 1975, fifth in 1978, sixth in 1974, 1976 and 1982, and ninth in 1970, 1980 and 1981.
Marcis competed in the Daytona 500 every year from 1968 until 1999. The 2002 Daytona 500 was the last time Marcis raced in NASCAR.
Late in the 1992 season, Larry Hedrick Motorsports hired Marcis to replace Greg Sacks in their No. 41 car, he ran seven races before being released. He returned to his car, who he had hired Jim Sauter to run.
Marcis started sixteenth in the 1994 Brickyard 400, but a crash during the race relegated him to a 41st place finish.
Near the end of his career Marcis landed the first major Internet sponsor in Winston Cup, Prodigy Internet. This company sponsored Marcis as an associate and primary sponsor between 1994 and 1996, to where at the 1996 Daytona 500 Marcis was able to display a showcar, a first for his career. Marcis had a horrific accident at Pocono in June 1999 when, after getting loose in turn two on the 91st lap, he overcorrected it to the right and slammed the wall head-on at a high speed, sending his car airborne and completely destroying it. He climbed out of the wreckage without injury. Marcis was frequently the test driver for the Richard Childress GM Goodwrench No. 3 of his friend Dale Earnhardt during the prime of his career. This agreement with Childress was made by Marcis to help fund his own race team, although he rarely had the time to test his own equipment.
Marcis finished his career at the 2002 Daytona 500, setting a record for most Daytona 500s run with 33. Goodyear awarded him with a special bronze trophy shaped like his signature Brogue shoe and Goodyear hat.
Marcis was a test driver for the IROC and the Nextel Cup series after his retirement from racing competition in early 2002. He currently resides with his wife in the Asheville, North Carolina, area.
