Its been a while since I've been with them, but I've previously been covered by a German company called ADAC. Its a long story, but basically to race round one of the German F1 race tracks, you needed breakdown cover with a local company. They charged about £70 per year, but ultimately upon further research it covered you throughout Europe - and thus people here got wind of it.
For breakdowns in the UK, an AA van would turn up - BUT on my experience you would be bottom of the priority list. I used them twice - first time had to wait 2 hours, 2nd time was something like 3.5 hours, and then there was debate about how much cover I had.
Both times I got a satisfactory cover, but the wait was too long, and so I decided to cancel it. There were also rumours of issues about recovery from abroad back to the UK - something about the worth of the vehicle vs cost of recovery.
I can't recommend them, but thought I'd share my 2 pence worth. I'd do much further research on them because its been a couple of years since I've been with them, and things may have changed. To research further I'd scour some of the VW enthusiast forums - thats where I original found out about the deal.
