Hi Gaz - welcome to TSN
We've not used Worthing Audi to have either of our cars serviced; they've not done enough miles yet... However, based on their the stuff we have used them for (warranty work on the A3, number plates and a wheel refurb on the A4) and the helpfulness of the service and parts guys I'll definitely be using them for servicing. The A3 is due a service in around 5k miles, and the A4 in 7k miles. Hopefully they won't both end up being due at the same time
As for specialsits in the area, again I've not needed one so have no personal experience; for my old E30 BMW I use a local garage in Arundel who have always been very good
