Scottish Aviation also had G-ASAL as a demonstrator, registered in '73 - a rare re-issue of a registration by the CAA, it was formerly SAL's demonstratror Twin Pin.
G-ASAL is still airworthy and based at Prestwick.
Have to say I don't think much of the Aston Martin Bulldog either - mind you I don't like the other angular sports cars that became de rigueur in the '70s!
