I have used the quick release a few time's . Took two of my cousins are ride in my 6 speed R/T . They are still talking about it . And I got in the back seat yesterday a few times to clean the inside of the rear window . It was so dirty . And put stuff on the leather to keep it from drying out . You never know if buying one of the early built cars is better or worse in quality . Hope they are all better . And just a defective part on yours.
