CTXX Motorcars Inc. was an automotive manufacturer based in Brenham, Texas. The company specialized in producing custom vehicles, notably the ACCobra, which was a modified version of the classic Cobra sports car.

CTXX utilized a body and chassis sourced from Everett-Morrison, a well-known manufacturer of replica cars. The company then incorporated its own custom elements, primarily using components derived from Chevrolet Corvette parts. This approach allowed CTXX to create unique vehicles that appealed to enthusiasts of high-performance sports cars.

The engines used in CTXX vehicles typically included a range of Ford options, from a turbocharged 2.3-liter four-cylinder to a powerful 460 cubic inch (7.5-liter) V8. All vehicles produced by CTXX were sold in fully assembled form, catering to customers looking for ready-to-drive performance cars.
