Are you buying from VW Leicester? If so is it a red 57 reg one? Because I bought my Mk5 there a couple of weeks ago and there was a very nice ED30 there!
If you plan to sell back into the VW dealerships, then they can be a bit sniffy about non-dealer stamps.For anyone else, (especially those who know what dealers can be like), a good VW specialist is actually better. Don't skip services, though.
