Hi Acme
Last time I was at D911 (which was quite some time ago) there were a couple of guys around the back (sort of) tinkering with what appeared to be some ferocious air cooled race cars, I had a chat to them and they were knowledgable, courteous and professional. It all looked rough and ready but I got the impression they were going places and dedicated to their craft.
I imagine that this was the foundation of D911 service dept, I would pop in and have a chat and formulate your own opinion, I always find this is the best way.
Because I have moved out of London, I have changed from JZM to Williams Crawford, Cornwall/Devon. I always found Chris/Steve and Jonas at JZM to be very helpful and likewise, Richard at W/Crawford, both companies have always got time for you and access to the workshops is always a way of assessing the quality of their work, never a problem at either of the above
Hope it all goes well at D911, who again, I have always found a very helpful company
Let us know what you decide
