I have not had any problems with west way in B'stoke, The service dept seem to be polite, car is done on time and technically they seem to know there way round the car, plus you get the stamp
If they offer a valet....and if your car cleaning standards are the same as mine.... don't bother
Just a general comment on any main dealer servicing, do any little things yourself a few days before.....such as Wipers, washer fluid etc.... then if you firstly point it out to them when you drop the car off then see it on the bill just complain and get it taken off again. My mate used to leave the empty packets/nearly empty items of whatever he had done in the passenger foot well as an extra hint.
I always state then if any "extra" work needs to be done then phone me BEFORE proceeding.
Just my two pence
