I kept thinking if I get a GTI then I will always wish I had got the Ed30 but as the spec is pretty big on the one im getting I think im going to be more than happy.
I could always get a remap for more power if I feel the need I suppose 
You have the same thinking as me with my 1st 2 GTi's, your never happy till you own one, ive been there, and to be honest or though a good spec car by the looks of it, you WILL always wished you had just waited a tad longer for a good spec ed30 to pop up. It cost me a few Grand in damage to my pocket, but i couldnt be happier right now ( maybe with a milltek fitted id be EVEN MORE happier).
Great car non the less, and WILL make you smile from ear to ear. Enjoy it, We all here are the lucky few that can afford a Mk5, so enjoy every drive like its your last!

By the way pics asap please. It is your duty
