As you can see from my avatar, my big brother owned a Vantage 4.3 manual for over 3 years. He traded it in for an SLK AMG when going for a new apartment as the parking space was too small for the AM. The apartment fell through (DOH)!! and he was gutted! They now have a place that can cater for a AM, and he is now on a mission to get shut of the Merc and get a AM on his drive again as he loved it!........ Sorry, going on a bit!
What I was getting around to saying is, if you want to have a chat with him and ask a few questions, he would be more than happy to chat. Just let me know if you would like to and I can PM you his details.
