NASCAR is well known for fast cars that handle well and for great drivers to handle them. They are looking for the top of the line in performance from man and machine. Therefore, the fact that the 1970 Superbird impressed them says a great deal about the overall value of what this car offered. The overall look and performance of this particular vehicle allowed them to continue pushing the limits on the NASCAR circuit.
One of the elements of the 1970 Superbird that you will notice is that it has a very high-winged spoiler known as a skyscraper wing. This design was to allow the right amount of air to go through the vehicle at top speeds. This helped NASCAR drivers to be able to go at top speeds while still maintaining control over their vehicle.
Another of the design elements on the 1970 Superbird was to offer exceptional performance on the NASCAR tracks. Around the front fenders you will notice rear facing scoops. To the general consumer, they appear to be a nice touch for the overall body design of the vehicle, yet the real purpose of them was to allow for tire clearance to be successful and for suspension travel. These two elements were certainly a significant value for NASCAR.
As with any muscle car, though, there is always room for something better to come along. The lifespan for the 1970 Superbird was short lived in the public as well as with NASCAR. It had to move over for other great vehicles that came along offering more power, that were lighter, and that had the newest technology offered for comfort and handling.
However, the 1970 Superbird will forever be a part of the NASCAR history. These vehicles are very valuable today due to the fact that they are a rarity. There are collectors that look high and low for them. They will buy this vehicle in any condition, from needing a complete restoration to one that has already been fully restored.
