Thanks Richard, much appreciated. I think the whole MSO is a predominantly US thing as I haven't come across it before in Europe. I will call the company that makes the car, Gardner Douglas (
www.gdcars.com) to see if they can help but I don't think it is something they have.
I am also hoping that some level of depreciation comes into effect as being 7 years old the parts aren't worth ANYWHERE near what they were when new.
