Discovery II needs fixing

I am quite new to Discovery ownership and have the 3 Amigo's, Oil leaks, Wet carpets and wheel issues. The local garage I have used is not a Land Rover specialist and struggled to realise some of the noises I had were the ACE anti-roll bars.
Question is:- Where in West Sussex / Surrey will I find an independent Land Rover (Disco 2) specialist? Looking for someone who will look after the Landy long term. I am in Horsham and soon moving to Godalming so that location would be great if anyone knows one.
