Ultimate Classic Cars

How Ultimate Classic Cars Started

Owner, Dennis Cahill, always wanted to own and drive a Cobra® Roadster. In 2015, after careful research, he purchased the best kit available, an LS-427 kit from Lone Star Classics. Shirley and Dennis fell so in love with the car and the driving experience they decided to create Ultimate Classic Cars and grow the car company to expand the replica car product line. They acquired the tooling and the staff and moved the car company to Boerne, Texas. Since starting Ultimate Classic Cars they have improved upon the GT-427 Roadster design and delivery of parts and service to their customers. UCC has implemented an inventory control system so that UCC will always have the parts you need.

Ultimate Classic Cars have improved their production capability by adding new body molds and new frame jigs. They have a new steel supplier that laser cuts all material to the exact specifications. Their new GT-427 has an even larger passenger compartment than previous models and leads the industry in passenger comfort.

Ultimate Classic Cars value all Lone Star Classic’s former customers and will strive to fulfill all of our customers’ expectations, both new and old, alike.

“Come see us and you, too, will love our replicas!”
