This vehicle is a one-off, Triumph TR250K race car designed to compete in just a single race, the 1968 Sebring 12 Hour of Endurance race. The car was the brainchild of Triumph's North American Competition Manager (R.W. 'Kas' Kastner), who hoped the car would enjoy tremendous success at Sebring, which would spawn more business for performance and racing products.

The one-off Sebring car was powered by a Triumph 2.5-liter six-cylinder engine and clothed in lightweight, custom aluminum bodywork wearing a design courtesy of Peter Brock. Kastner was able to secure some financial backing from Triumph for the project. Kastner, Jimmy Coen, and Bob Avery assembled the chassis, and the custom aluminum bodywork was fabricated at a local shop. Brock's race shop completed the assembly of the body and the chassis.

The design created by Peter Bock is elegant and aerodynamic, with a low hood line and a moveable rear spoiler. The spoiler, in design, was supposed to allow the team to adjust it for best aerodynamic performance.

Construction of the car was completed just in time for Sebring, with very little time for testing or fine-tuning. During practice at Sebring, it was discovered that the car suffered from cooling problems. Work continued and the car returned during qualifying where it qualified 39th out of 68 starters. The car, wearing race number 47, was officially entered by 'Leland Motor Corporation - Teaneck, New Jersey' and assigned to compete in Sports Prototype (Group 6) Class 10. The car was driven by Jim Dittemore, Bob Tullius, and Mike Rothschild. The Triumph TR250K was one of five cars competing in the class, with the other four vehicles being Porsche 907 works entries. Two-and-a-half hours into the twelve-hour race, the car encountered problems when one of its rear wheels broke apart, causing the car to spin around. No body damage occurred, but it did cause damage to the suspension which caused the car to finish the race prematurely.

Though the car endured disappointing results at Sebring, it was featured on the cover of Car and Driver magazine's April 1968 edition. It was also shown throughout the country, making appearances at the Detroit Auto Show and other events.

At some point during the car's history, it was part of the Blackhawk Museum's collection. Currently, the car is in restored condition.
