So Markerstudy wanted me to give it to the cowboys at Prestige in Northampton (who aren't Audi approved) or bundle it up to Leicester - neither work for me, so I insisted on Castle Coachworks who are Audi approved but up until recently were on the Vision network and on the approved supplier list for Markerstudy. Being as they aren't on the Markerstudy list and my insistence, I may be liable for any difference in repair costs between their suppliers and my chosen supplier.
I tried arguing the toss but they pointed me to a line in the terms of business when I took the policy out - gits.
Moral of the story, read the small print and be careful who you chose, make sure you switch if you aren't happy when it comes to renewal time
