197: 6 year service recommendations?

I'm going to be a pain. Last year I had my car services at ren7oaks and can't fault them. If it weren't for the fact I've moved out into Hampshire I'd be going back to them (I still might)

The time has come for my 197 6th service as, although we aren't a year later it is about to hit the magical 12k.

Can anyone recommend me an indie specialist within reasonable distance of farnborough/Guildford?

ktec was an option but they seem to charge a lot for labour on the service compared to ren7oaks labour charge.
 
Yep 12k since its last service. It's actual mileage is almost 50k now.
I'll have a peek at rentech and woodford too as chertsey isn't to far away.
