I think we have to be fair and say that most times its not the "total" dealer experience that's at fault,but mainly just the service department.
Take my local VW dealer. Their sales department was superb when I bought the Golf and then the Wifes Polo, courteous, professional and a real good price. Similarly, the guys on their parts department are again superb. Know their stuff, will take as much time as possible looking up parts, always have a laugh anda joke with them, and they always give me discount.
Even the service reception staff are good, the only problem seems to come down to "some" of the muppets in the service bays themselves. I'm sure there are a many excellent and totally professional techs as there are muppets, it just seems I always get the muppets. This wouldn't be so bad if their worked was checked, but it doesn't seem that's the case either !
Like I said, it's a real shame as the rest of the local dealer experience is usually excellent.
