Check out Sterling Replicars' quick release. Lee Dahmer has designed a release that uses a black aluminum ring which encircles the steering wheel shaft. You simply pull the spring-loaded ring towards the steering wheel to release it from the shaft. Most people don't even notice that it's a quick release it's so inconspicuous. It also allows you to mount the "AC" or another Cobra emblem on your steering wheel.
Most of the other quick releases I have seen use a rod that sticks out the side of the steering wheel shaft and they don't allow the mounting of an emblem. These are not too pleasing to the eye IMHO.
