uses five different schemes with color differences to promote four different brands—Express, Ground, Freight, and Kinko's. (A fifth scheme was used in 2005 at Darlington, and is a special scheme, to promote the St. Jude Hospital they support in Memphis.) Those are not "special" schemes, but are co-primary schemes to promote various products by a sponsor who may be willing to use the broadcasts to promote their wide variety of products. The sheer number of special paint schemes has led to criticism that they are no longer "special" at all. However, it should be differentiated between alternating sponsors, different products on cars (especially promotions for special products), and the true special paint schemes, which promote special events. IndyCar Series Though not as widespread as NASCAR, cars in the IndyCar Series have also participated in special paint schemes. Most that have been used have featured a "retro" or tribute paint scheme, depicting a notable car from the past. In most cases, the sponsors are not the same but carry the current sponsors' decals on the classic liveries. 1987–1991: Vince Granatelli and later UNO/Granatelli entries sported a "throwback" paint scheme which featured a day-glow orange, similar to that of the STP Turbine cars of the late 60s, and other Andy Granatelli entries of the early 1970s. 2000 Indianapolis 500: Hometown rookie driver and co-owner Andy Hillenburg fielded a "throwback" entry named the Sumar Special, a gesture to the car driven by Pat O'Connor which won the pole position in 1957. 2001 Indianapolis 500: Billy Boat fielded a "throwback" paint scheme that resembled "Calhoun," the car driven by 1962 pole position winner Parnelli Jones. Boat's car was nicknamed "Calhoun II." 2007 Indianapolis 500: Ryan Briscoe's entry at Luczo Dragon Racing was painted in a "retro" paint schemes to resemble Rick Mears' 1988 Indy 500 winning car. It was the first of a small trend of similar instances. 2008 Indianapolis 500: Marco Andretti's car was painted to promote the movie Indiana Jones and the Kingdom of the Crystal Skull, and his racing suit was designed to resemble Indiana Jones's outfit. 2009 Indianapolis 500: Rahal Letterman Racing's DAFCA Special for driver Oriol Servià was painted to resemble Dan Gurney's 1968 Olsonite Eagle, which finished second in the 1968 Indianapolis 500. 2009 Edmonton Indy: Will Power drove a Penske Racing Verizon entry with the retro Penske Truck Rental paint job, resembling Al Unser's 1987 Indy 500
