I picked up my new baby on Friday from Motorpoint in Glasgow; from start to finish I've been thoroughly impressed with them; they are the only "dealer" in my (admittedly limited) car buying experience that I would go back to.
When I got there on Friday, the car I'd purchased (and had shipped up from their Welsh depot) turned out to have no AC; I merely mentioned this, and they started searching for one that did; with luck there was one with the exact spec that I was looking for on site; unregistered and therefore £1k more than my 06 plate initial choice.
Within two hours they had it registered and taxed, refunded the £150 delivery cost for the original car and I was away. For a newer plate and the full dual zone climate control, I was more than happy to pay an extra £850 or so!
In short, great service and I would definitely go back. Two caveats though... there's now an Irish spec 06 plate with a sunroof and no AC floating about - I'd avoid it - also I'm looking for a GTi manual in English rather than Dutch!
hope this is helpful to you,
