4: 1964 Mercury Comet Cyclone
The Mercury products of the 1960s were some of the best automotive products to come out of Detroit. This was at a time when Mercury attempted new advances in styling and performance. The 1964 Mercury Comet Cyclone took the styling of the decade and infused it with stellar road manners and off-the-line speed (via Old Ride).

The 289-cubic-inch V8 is often credited as one of the best engines to come out of Ford. Dubbed a compact car, the Mercury Comet Cyclone was anything but that. However, the unique design and build quality took the car to the next level. Enthusiasts are starting to recognize this car, and the values will rise.
