The team returned to the Indy 500 in 2000 with an entry for Johnny Unser who started 30th and finished 22nd in the team's first Indy Racing League race. They returned the following year with inexperienced rookie Cory Witherill who made an improbably successful bump day run to get the Regency machine into its 3rd Indy 500. Witherill brought the car home in 19th position. In 2002 Regency fielded a car for Hideki Noda in the last 3 races of the season with little success. The team participated in Toyota Atlantic in 2002 after Indy Lights' demise and apparently shut down shortly thereafter.
