Car: Chevrolet Caprice 454 Turbo Jet
What makes it special: For 1970, the Chevrolet Caprice received a minor facelift, now sporting a "conventional bumper underneath the grill" look, as opposed to the prior year's "wrap around" front bumper. In addition, it now featured bumper surrounded vertical taillights.
What made it famous: For 1970, the top of the line big block 427 V8 was replaced by a 454 Turbo Jet V8 as top engine. It also required Premium fuel to feed it.
Why I would want one: It's one of the seldom seen larger Chevrolet models, not just as a Caprice, but in general. You just don't see very many 1970 Chevrolet Caprices around anymore. Plus, the 454 Turbo Jet V8 could be mated up to everything from a "three-on-the-tree" manual column shifted set-up, a console mounted 4-speed manual, or your choice of two-speed Powerglide or 3-speed Turbo-Hydromatic Automatic transmissions.
Fun fact: The "Caprice" name was coined by then Chevrolet General Sales Manager Bob Lund, after a classy New York City restaurant he frequented.
