History

Dick Sweebe began working for International Harvester in 1972 and served in several capacities before purchasing his first dealership, Mid-America International Trucks in Memphis, TN in 1982.  This timeline briefly describes our growth over the past 27 years.
  • 1982:  Acquired dealership in Memphis, TN
  • 1995:  Acquired dealership in Little Rock and Pine Bluff, AR
  • 1996:  Acquired dealership in Russellville, AR
  • 1998:  Acquired dealership in West Plains, MO
  • 1999:  Created Diamond Companies as the holding company

  • 2004:  Acquired dealership in St. Joseph and Joplin, MO and Lowell, AR

Until January 2008, the dealership locations operated as three distinct entities: Mid-America International Trucks, KCR International Trucks, and Diamond International Trucks.  In 2008, Diamond Companies underwent a re-branding initiative in which all dealerships came under the same unified name, Diamond International.

There are 6 idealease locations that operate under the name Diamond Idealease.

The bus franchise in Conway, AR has remained the same, Diamond State Bus Company.  They are the sole IC franchise in the state of Arkansas and have exclusive rights to the Eldorado bus line in Arkansas and Tennessee.
