If you don't mind a little further I can recommend Rayner in Newbury
The Good Garage Scheme: Rayner Diesel Services (Newbury)
Don't let the diesel part put you off they are good at diesel & petrol just had the Berlingo cam belt auxiliary belt idler and water pump done all at quoted price all in time and they showed all the replaced items without being asked.
Asked them about crossfire - answer yes and we use Mobil 1 - fair enough
Reception is Debbie 01635 46323
Newbury center is a short 10 mins ish walk plenty to see and food to eat or just wander into Sainsbury coffee shop around corner
