Robert C. Frey (born October 25, 1950) is a former American racing driver from Elyria, Ohio.  He was a notable sprint car driver who won some of the country's most prestigious races when he attempted to try his hand at CART Championship Car racing in 1980.  His first attempt to qualify for a race at the Pocono Raceway ended in a practice crash.  His first race came in September of that year at the Michigan International Speedway and he finished 17th.  The following year Frey notched his best CART finish of 13th at Phoenix International Raceway but then failed to qualify his eight-year-old Eagle-Offy for the 1981 Indianapolis 500.  He returned the week after the Indy 500 and drove in the Milwaukee Mile race, finishing 17th.  Frey returned in 1982 with a much newer 1981 Eagle chassis but failed to qualify for both the Indy 500 and the Milwaukee race, after which he returned to sprint cars. <SEP> The Caesars Palace Grand Prix was a car race held between 1981 and 1984.  Nissan/Datsun was a presenting sponsor of both races.  For the first two years, the race was part of the Formula One World Championship, before becoming a round of the CART series in 1983. <SEP> Jeff Wood (born January 20, 1957) is an American former race car driver born in Wichita, Kansas.  He was Formula Atlantic Rookie of the Year in 1977.  He drove in the CanAm series for Carl Haas in 1981 and finished 5th in the series behind Danny Sullivan.  In 1982, driving for Bob Garnetson Racing, finished 3rd place in the 24 Hours of Daytona.  He then drove in the Formula Atlantic West Series where he won the 1985 championship.  He returned to CART in 1987 and made 4 starts for Dick Simon with his best finish being 10th.  He was away from the series in 1988, then returned in 1989 to make 5 starts for Gohr Racing, where he finished 12th at the Michigan 500.  In 1990 he drove for a new team, Todd Walther Racing, where he made his first attempt to qualify for the Indianapolis 500, but crashed in practice.  He made 10 other starts, with a 10th-place finish at Phoenix, finishing 22nd in points.  In 1991 he made 8 starts for Dale Coyne Racing, Arciero Racing, and Euromotorsports with the best finish being 13th.  7 starts in '92 for Arciero netted Wood a 12th-place finish and a single point.  In 1993 Wood attempted a nearly full season for Andrea Moda Formula/Euromotorsports but failed to qualify for 6 races and only made 8 starts and again failed to score points.  He then made his CART debut in 1983 at the Caesars Palace Grand Prix driving for Dan Gurney.  He made four more unsuccessful starts in 1994 for Euromotorsports in what would be his final races in the series.  He was named to an entry for the 1996 Indianapolis 500, but the car failed to appear.  His best finish in his 49 CART races was an 8th place that came in his second series start back in 1983 at Laguna Seca Raceway. <SEP> 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.
