Thanks everyone. You've all been really encouraging. I'm ideally looking for a Black coupe if not gunmetal grey would be nice. I've found they're pretty hard to come by which is half the reason I find them so alluring as you rarely see them on the road.
Do you find as they are quite rare servicing and upkeep can be expensive?
No not at all, at the end of the day they are Merc engine and running gear, lots of Merc or patten parts available and if you have a friendly garage you can take it too you should have no problems.
