I second the Tucker. It was one of the first cars to place an emphasis on safety, with a padded dash and deeply recessed controls & gauges, a collapsible steering column, and a survival-cell passenger footwell, which does certainly add interest. The center headlight turned with the steering wheel and automatically lit up at night. It had a four-speed transmission in an era of two- & three-speed units. But perhaps the most immediately noticeable feature is its 334ci flat six, apparently a helicopter engine. With 166hp and an undisclosed (but apparently quite adequate) level of torque, it could hit 60mph in 10 seconds and go on to a top speed of 130mph, both of which were blazingly fast for a passenger car in 1948 and still fast enough to keep up with traffic today. This is despite the car's overall weight of over 4,200 pounds, and the fact that the engine was tuned for low revs and steady running rather than outright speed.
