Just had my 25k done at D-ick Lovett Swindon - pretty good actually. Friendly enough staff, booked me in quickly, sold a set of wipers without fitting them, nothing much else to report.
The servicing is still done a mile down the road from the MINI place at their BMW showroom but they said MINI servicing would be moving at some point.
Spent more time looking at the BMW M6 than the MINIs in the showroom (bit of a worry...) but did drop in at the Porsche garage as well, it's right next door!
Oh, my car wasn't cleaned after its 25k and no wireless internet whilst you wait, so the service has room for improvement at Swindon.
