The super-sonic Bloodhound land speed record project has stalled.
It ran into financial problems this year and engineers have been unable to find new sponsors for the 1,000mph rocket car, partly developed in Swansea.
Now the car is up for sale and offers of £250,000 are being sought.
The team behind the project over the last four years has hand-built the car with specialist support from universities, industry and business as well as private funding.
It underwent testing in Newquay this summer and work had starting on preparing an 18km course in SouthAfrica for the speed attempt next year but rising costs and financial climate conspired against the project.
It is still possible the project might be rescued before the car and team are split up but it seems unlikely.
Aerodynamics of the car were developed in Swansea University.
