I don't disagree that a bit of time and money have gone into it, but when was the last time you saw someone get the money back that they put into the car? Some might get close but the majority don't in my experience. Either way, it's a nice car, and I hope it gets sold to someone who'll enjoy it.
I have but unfortunately it'd need to be thicker than 1mm Aluminium to be strong enough to hold the cable in place. I tried fabbing one up out of steel but I don't really have the right tools and I was getting pretty frustrated :(
