Mike,
I bought an auto box from a guy who changed his car into a 6 speed manual. It was a full MB conversion kit that came from Germany with all the necessary adaptations included ( if I remem correctly it was around 12.000 euro box and for the job). This was about a year ago. He was very very happy with the change....much smoother and great performance without the high revs which was what bothered him in the first place. He is close to 80 and said he betted on comfort and got it.
Question here is if that car had a good quality box and job done.
Btw. I did most of my schooling in, from age of 10, Durban and then university at UCT. Great country, I follow the news closely with lots of old friends down there , hope the next few days show things are pointing in the right direction...
Regards
Pedro
