So long as the car they looked at for me today is one they can confirm, I've just jumped ship from the BlueGT I bought new in July 2014 to a new Polo GTi - some sort of promo weekend though I never believe that hype, basically they are selling cars that are in production but not yet accounted for or have perhaps been cancelled by the customer.
So with a little over 2 years of age on the BlueGT (which is a fantastic car, love it!), and a small £500 deposit contribution from me, the 3dr GTi is going to set me back £265 per month. It had four-corner parking sensors included, CarNet (which being the only Windows Phone user in the UK, I can't use!) and is in red. No other additions, though I'll be opting for car mats and the 2yr service plan at pickup.
The BlueGT (also 3dr with a few option packs) was costing me £247 a month so not really anything of consequence in the change of costs, plus another free years insurance and I'm doing way less miles now so not as much need for the fuel savings on the BlueGT which saw me averaging 49mpg after two years.
Really looking forward to it, should hear on Tuesday next week that they've secured the car and when it'll turn up

Seems the new 1.8 engine is great and I'm hoping the larger brake discs give a bit more sharpness than the smaller BlueGT ones. It's basically the MK2 Golf GTi I never managed to own!
