I phone my local VW stealer and enquired about the price for changing the driveshaft boot and was told £190 plus cost of boot ~ £25 so £210 - £215 all in, then phoned the VW dealer 30 mins away, and was told £150 all in, so went with £150 and when came to pay, "actually sir it was less than we thought, it is actually only £140" !! and what's more, both dealers are owned by inchcape, guess which one gets my business?
And the service reception girls at the cheaper garage are real hotties (sorry to female forum members) so added incentive, 25% less and very nice reception staff!!
I always phone around, actually the old motorworld VW on the iffley road in Oxford used to be even cheaper still, but has changed hands now, prices have shot up and I don't work in Oxford anymore (thank god, traffic was horrific)
