Just wait till he joins the vw forums! when I had my VW's (Mk3 gti golfr and passat pd tdi estate) those forums were as full as any other brand with cars with faults! Strangely mostly the same faults as alfas have (yes, Bosch parts!).
The only cars anyone I know has that have been faultless are 1) the wifes mazda mx-5 and 2) Stepdads Citroen C5.
I have mates with new golfs, passats, Audi a3, Audi S4, Honda CRV, Skoda Octavia, Jag x type, ford focus, pug 207, land rover discovery, volvo v70, volvo s40, audi tt3.2, BMW M5, BMW 330C (diesel), Jag XKR and so on - all have gone wrong at some point!
