Got to drive a 5 door GTI today at Whitchurch VW. Impressions, very good. In comfort mode the car rides superbly on rutted typically poor B roads (on the 18"). Acceleration is excellent, plenty of grunt. Seats are good, but lack upper back support. Interior quality is OK, not great, but on a par with BMW. Pro satnav looks very good. Brakes are very aggressive, but nicely positive, only need a slight touch. Manual gearbox is spot on, great action, easy fast change.
Overall I thought it a quality device, exhaust note was a bit too muted to me, but sounded good nevertheless.
If you're on the fence, just buy one, you will not be disappointed. Can't wait to get mine, week 36 now...
