Im 20 and the N/A is plenty good enough power. I have had 4 other cars so far(That I saved for and bought myself also) and driven tons from a 80's rabbit pickup to a '06 sti. You wont be dissapointed on power from the N/A, around town its plenty quick enough. The main reason I am ok that I didnt buy a SRT is the stick. All of my cars have been and will be manual, except of course for my wife's vehicles. Besides, you can buy a N/A and get used to it then jump on the BEGi turbo down the road if your not satisfied.

In any case good luck and be safe.
