Can't be arsed to do the maths but for me:
GTI or GTD, not fussed
3 or 5 door, not fussed, kids are bendy so can cope with either.
possibly white, possibly red but would probably prefer a grey as I detest cleaning cars yet I like mine not to look dirty!!

Manual as the road test bit I read said the 6th gear is silly high and I don't want to be arguing with the car all the time as I can't do that and argue with the wife at the same time.
Basic Nav as I'm a bit thick and crap at directions but far too tight to pay for the bells and whistles nav.
Park Assist as I can't drive properly and I'm old and lazy, and really just because it's a gimmick and I fancy it!!
Rear camera maybe? Dunno.
19" wheels silly expensive on top of existing 18" option so would just transfer my BBS's over and be smug.
Not sure about Performance Pack. Might bite the bullet if the deal was a good one.
That's probably about it.
Might give a few dealers a ring to see what my rapidly plummeting GTI price to change would be. I'd want one of the first ones if I was going for it otherwise I'd just do my usual and pick up a demo car off a dealer who's keen to deal.
