In 1997 he made his first start in the Indy 500 starting in the 35th position after league and speedway owner Tony George added his and Lyn St. James' car to the field because slower cars than theirs were guaranteed starting positions because of prior races.  He went on to finish 18th, his best "500" result in 5 starts.  Unser drove the majority of his IRL races for Hemelgarn Racing and in his 14 career IRL starts he had a best finish of 9th in his very first series start in 1996 at Phoenix International Raceway.

He made 3 CART starts in 1991 but was badly injured in a practice crash for the Indianapolis 500, when his car veered sharply towards the entrance of pit road at the exit of Turn 4 and back-ended the fence, only to careen across the pit lane and smash virtually head on at sizeable speed against the edge of pit wall; this second impact tore off the front of the car leaving Mark's legs exposed.  Amongst the injuries he suffered, the most severe was a broken neck.  He was largely out of open wheel racing until the 1996 Indy 500 where he drove for Team Menard though he did try to qualify in the 1992 Indianapolis 500 for Concept Motorsports in an outdated Lola/Buick.

Garza claims he does not know how the error occurred but he did not notify officials of the error.  He finished 10th in the 1984 Indianapolis 500.  He led 13 Indy 500 laps.

Phil Caliva: Phil Caliva (born January 1, 1945 in Palermo, Sicily) is an Italian-born American racing driver who competed in the CART Championship Car series from 1979 to 1984.  After racing in the North American Formula Super Vee series in 1977 and 1978, he made his CART debut in 1979 driving for Spike Gehlhausen at Ontario Motor Speedway.  Caliva returned the next year and made five starts for Bill Alsup and tried but failed to qualify for the Indianapolis 500.  Caliva attempted a second time to qualify for the "500" for Alsup in 1981 but again failed to make the field.  He made 3 more starts later that year, including his best series finish of 8th place at the Michigan International Speedway in July.  He tried 3 races including the Indy 500 in 1982 but failed to qualify for all of them.  He tried the Indy 500 again in 1983 and missed the field again, but made the race at Riverside International Raceway in what would be his last Champ Car start.  He tried the Long Beach race and the Indy 500 again in 1984 but again missed both races.

McCormack Motorsports: McCormack Motorsports is a former Indy Racing League team owned by Dennis McCormack that operated from 1996 to 2001.  Based in Avon, Indiana, the team debuted at the 1996 Indianapolis 500 with a car for Randy Tolsma, however, it failed to make the field.  For the 1996–1997 season, the team used 3 different drivers.  Raul Boesel drove the entire 1998 season for the team and finished 20th in points with a best finish of 8th.  1999 was another season of instability as the team saw 4 different drivers start a race for them and one other driver, Nick Firestone, fail to get his McCormack entry into the Indy 500.  2000 again saw 3 different drivers drive for the team and relative instability and lack of funding, along with two of its cars, this time driven by Ronnie Johncox and Robby Unser again fail to qualify for the Indy 500.  This was largely due to a disastrous experiment with using the uncommon Riley & Scott chassis.  The team also formed an alliance with the Byrd brothers of Byrd Motorsports and fielded the #30 car for a revolving door of drivers including Johncox, Jon Herb, and J. J. Yeley.  2001 was the team's final season.  The team shut down after its car driven by Brandon Erwin failed to qualify for the Indy 500 and then the next week at the Casino Magic 500, where they were woefully off the pace.  The team's best finish was a 5th place by Boesel at the 1999 Indy 200 at Walt Disney World Speedway.
