My VW Bug (1969) likes to randomly adjust my seat back angle as I am driving.
I'll shift and my seat will go "POP" and ack now I am all bent backwards :-D
I am 6'6" and its not 'comfortable' to drive with my seat all the way back in the mercedes although I have no problems with pedals.
My favorite is when I was in the Fred Meyers parking lot with some friends and put my seat all the way forward, up, and whatnot and was driving with my head sticking out the sunroof around the parking lot (very low speeds

)
I usually have the seat about 2-3 inches from the rear stop and the rest is all the way down becuase my head likes to bump the roof if I use good posture.
YOu should bring that coupe to the meet..it sounds nifty
