It was a brilliant (and beautifully designed, meticulously detailed) toy, wasn't it? I seem to recall that it came complete with tiny figures of Batman and Robin as well, which could be removed from the car. Great car, and almost indestructible.
Re Batman, as a kid, I took the TV series entirely seriously. Indeed, until Michael Keaton and Jack Nicholson faced off in Tim Burton's take on the character of Batman, a movie made even more compelling with Anton Furst's stunning and slightly sinister vaguely Gothic reincarnation of Gotham City, like you, for me the character of Batman had been defined by Adam West.
Actually, a little later, I was also given a die cast model of the car from 'Chitty Chitty Bang Bang', which had wings that could the folded and unfolded. Another exquisitely designed toy.
