No one can make the choice for you. You have to decide for yourself.
I wasn't expecting any differences from the car i saw over 6 months ago, I ordered it on the basis of how it looks. I like the look of the Mk2. I'd happilly have an FR or a TFSi.
But i'd rather have the looks of the FR or TFSi with the 240PS performance and the 300hp tuned potential of the Cupra.
The Aero kit does very little for me, it reminds me of a bottom feeder, just my opinion of course. But the only aspects that kit has going for it, is the skirts and possibly the rear wing, the rest i'd rather not be on my car.
I'm also keen not to have a car that screams, look at me, steal me, mug me take my car. And if the Cupra looks a little plain jane, thats fine by me, as long as it goes like a scalded cat.
