I reckon £26/£27k basic for the Mk7 plus options.
You'll pay all that for example and still have to pay extra for cruise control, sat nav because it's a GTi. Next door's Passat estate has those as standard.
My plan at present is to mod the Mk6 and run it into the ground ad replace the wife's 123 cab with another BM as I refuse/am unable to pay £27k plus for a GTi when I could get a quicker car for £20k from countless other manufacturers. The VW badge is not worth in my eyes what VW reckon it's worth.
