Spotted this today at JCT Rotherham...
Thoughts - looks bloody awesome! Liked the Pure Grey which I thought might not look good. Rear diffuser in gloss black looks great, very pronounced as opposed to the std plastic one on the normal GTI. Interior is lovely, feels and looks more expensive than the stock cloth. And not as orange as some pictures look. Not sure why the mirror caps are a greyish colour and not gloss black to match front lip/sides/rear etc. Wasn't keen on those.
But with options, this was £40k! I'm guessing you'd get some discount though.
Making that look pricey was this... 19 plate, white, manual, 3rd, no keyless for £27.5k.
