S3 is a great car, and vv quick.
you really need to drive it though, as it is not as tactile as the gti. very comfy and nice place to be, but not much feedback from the steering.
i test drove an S3, but went for the ED30 instead, as it drove better for me ( and was £5k cheaper).
would i have an S3 now ? - damn right i would.
I am sure you will notice the difference in power
