BCA's Classic and Historic Division donated £2,000 to the national organisation Motability at a classic sale held at the Blackbushe centre.
The company contributes to the charity for every catalogue that it sold throughout the annual classic and historic auction programme.
Tom Madden, BCA's director of consumer affairs, was on hand to present the cheque to Hazel Gotfraind, Motability's fundraising and marketing director, at Blackbushe.
He said: "All charities need a continuity of financial support and BCA has been able to provide this commitment over many years.
"What this most worthy organisation gives is not simply a grant to help disabled people with the costs of adapting vehicles for their needs, it is the gift of freedom to travel that we all take for granted."
Hazel added: "I would like to thank BCA Europe, and particularly the classic and historic division, for its continued support over the years.
"This substantial donation will enable many disabled people and their families to become mobile.
"By providing affordable independent transport, the Motability scheme opens up opportunities for hobbies, education and employment, helping disabled people to improve their quality of life immensely."
Since 1990 BCA has donated more that £30,000 to Motability through this fundraising initiative.
Its commitment as a regular corporate donor has enabled hundreds of disabled people to achieve greater mobility.
