I've had really good service from my local dealer, but as someone pointed out not so long ago - we're so used to cr@p service everywhere we go these days that when someone does do what they're supposed to do, people rate it as 'good'.
In the past 2½yrs my local dealer has replaced tyres free of charge (uneven wear on front tyres), replaced a misted up headlamp f.o.c., replaced corroded alloys without even asking to see the car first, valeted the car whenever I've been there, arranged test drives at very short notice, and given me an SC430 and GS300's as courtesy cars. So I really am being honest when I rate the dealer as they really have gone out of their way to help. Maybe I'm lucky and this isn't the norm any more?
Problem is, I know so many friends and colleagues with new BMWs, Mercs, Audis, Fords, VWs etc., who have had nothing but grief (my other half included). Hehe... mate bought brand new Ford Mondeo ST220 Estate. After 2 months it was off the road for six weeks because of steering problems. He was given a Ford Ka to use for four of those weeks, and was offered 10% off his first service - that worked out at £90 so he got a £9 discount!!
