Out of of interest I just spec'd a scirroco to the same spec as the golf R I'm ordering
Why is the sat nav unit £400 cheaper
And why do they get the ACC included and the winter pack as standard?
A saving of just over a grand 
ACC has always been standard on the UK Scirocco. Not sure about the Sat Nav as its the same unit. I was surprised at how expensive the Scirocco is anyway - so at least its getting a few options bunged in!
I've been looking through the Golf's 'standard' features trying to work out where the extra cash is going. 18" Wheels as standard instead of 17" on the GTI. Xenon lights standard (£1000 on GTI). 4WD. Bigger Brakes. Flat Tyre Indicator. Extra 55bhp. Different bumpers / seats / R badges. Is that it?!?!

I just can't get over the £3080 for Recaros! On the S3 they're only £1500 - but then I suppose it starts with leather as standard.
Yep - the S3 does seem well priced against the Golf - but the S3 is damned ugly, and will be restyled next year. The Golf
should get about 3 years before a newer model!
