Yes, but many years ago.
More recently the ex-owner of my current car (who lived in Paris) advised me that he had experienced problems and afterwards would only take the car to Belgium for work.
I also have a very low opinion of their views on Aero8s given the write-up on buying a used Aero8 that featured in the avril 2008 Sport Auto magazine with erroneus comments from one of their staff. If you don't have a copy of this article I can send it to you.
I do my own maintenance and if I have an engine problem that I cannot diagnose use a friend's diagnostic computer to resolve.
Of course your Aeromax is under warranty so I presume that may affect how you deal with any problems. Anyway good luck getting it sorted.
Cheers
Philip
