Porsche 912
There was a time when people wanted new cars, and previous years' models could be had for pennies on the dollar — that time is long past. With vintage Porsche models skyrocketing in value, they are as much an investment as a an automobile. Bucking the trend, John Benton purchased his 912 (the four-cylinder variant of the flat-six 911) at the age of 23, and the two have been motoring together since.
