This is GM’s incredible secret stash of cars
Take an undercover trip round the General’s jaw-dropping collection of Cadillacs, Corvettes and crackpot concepts

Each car in the collection is fired up at least once every 90 days, with Wallace driving many of them on the road. But which is his favourite? "Ah, they're like children," he smiles. "If you've got more than one kid, one's your favourite one week, another the next. But I like cars you can get out and drive. The stuff before 1920 is a bit... tricky."
Without getting too misty-eyed, the heritage hall isn't merely a hypnotic collection of Caddies, Corvettes, Buicks and the rest, but a barometer of the rises and falls of the American car industry - perhaps even America in general - from the highs of the Twenties to the low, low lows of the Eighties.
