The Cardenas organization was established by Mr. Renato E. Cardenas in May of 1971. Formally, Valley Buick Company, Cardenas Motors Incorporated was located on Elizabeth Street in downtown Brownsville, Texas. The dealership sold Buick, Opel and American Motors cars and Jeeps, and quickly built a reputation for reliable service, quality workmanship and dependability.

In 1982, Cardenas achieved a new level of success with the launch of a totally new automotive product to the Rio Grande Valley: Isuzu cars and trucks. The following year, Cardenas acquired Dodge car and truck franchises. This momentum carried on in 1988 when GMC medium duty trucks joined the Cardenas line.

Cardenas Development Co Inc is a real estate agency located in Brownsville, TX.
