Agreed Taffy, I was thinking more along the lines of who does the work, knows the parts (BMW has a BIG parts bin so you need to know which is which) and how far you need to move the car if it does break down. The lack of Morgan dealers near me is making servicing and repairs a bit of an ache.
£1400 is a fair bit more than an Aero but I guess they are reflecting the cost of repairs due to lack of body parts?
