Came across this on Youtube. Not a wedge unfortunately, actually a Europa, but I guess if you have the time to find the gem's, there's potentially some good ideas contained within these video's equally applicable to any car.
I've only watched the first few minutes of Episode 57. Started being very impressed by the innovative approach of this guy, then around 2 minutes in, I had to watch through fingers with hands in front of face
If nothing else it's entertaining
Request to all: There's far too much to watch - Must be over 24 hours of it. If you find interesting / relevant bits, post the episode number and running time in this chain for the good bits.
