I would not lump all the dealers together and class them as VW.
Some dealers are quite good if you can find one with a tech that knows what hes doing and has a passion for the job.
Its finding the good ones.
Also some may have a great sales side but a crappy workshop side.
Its finding the good one out of the rotten bunch thats the v.v.v.v.v.v.v.v.v.v.v.v.hard part
