turbo lag? both the wrx and sti have a slight bit of lag and the civic isn't turbo'd.. so I dont see where that would compare.
This really sounds to me like you're trying to convince a parent or guardian to let you have a turbo'd awd vehicle for your first ride.
Based on that I have to ask, is this going to be your first car?
If so you might want to consider something that isn't as .. well.. hard to insure for the younger guys "AND" a little more forgiving to operator error. As good of a driver you might think you are.. your not.. we've all been in that spot all it gets you is a free trip into a guardrail, ditch, another car.. etc. For some of us it was worse than others. Mine was a ditch.. and in a car MUCH slower than my wrx. If I had this car at 17 I'd have killed myself in short order during the learning process.
There are literally dozens of reasons why the wrx is better than other cars in its class.. but whether its better for the driver in question or not is kinda up to the guy with the money. I'm def not trying to rain on the parade.. the wrx is a wicked car, and enthusiasm toward it is quite welcome.. but if "financial aid" has your safety and best interests in mind.. he's not going to want to put you in a awd rocket right off the bat.
are you looking used or new?
