The top prize of the £90,000 car has been donated by entrepreneur and TMCTF trustee David Weil: he wants to see it raise more than twice its value for the fund.
At least £9 from every £10 ticket sold will go directly to the trust, said head of fundraising Richard Kenworthy.
“In effect, you are donating at least £9 to the RMCTF, with the added chance that you may also become the proud owner of this fantastic vehicle.”
If a brand-new Aston Martin isn’t for you, a £75,000 cash alternative is up for grabs.
You have to be quick, though: closing date for the competition is 4 September, and the winner will be announced in 11 September.
