As a general rule, work by privately owned independent specialist is usually of a higher standard than main dealers.
oh really my service book is all vw (well the 2 stamps that its got lol) so i thought it be better to go back only for that
in my mind im telling myself it will be worth more money when i come to sell but i bet not
I for one count the stamp in my log book by a well known VAG Indy Specialised as a good thing and something that shows the car has been looked after by someone who knows what their doing. I would be much happier seeing their stamps in your book than a load of generic VW stamps with the work being carried out by god know who, all IMHO.
I use a VAG specialised and won't go to a main dealer for the very reason you mention but also because of the price. Recently had my major service, fuel filter and brake fluid change at JKM and was well over £100 cheaper than the quote I received from my local VW main dealer.
