^This. The M3 is definitely the better straightline performance car out of the box and it should be seeing that a typically optioned M3 is over twice as much as an STI and has significantly more power even though it is about 300lbs heavier.
An M3 traps at around 114mph and an STI around 101mph. It would take the STI an extra 110-120whp to get in the 114mph trap range. Can you do that on a stock block? Sure, but your days will be numbered no matter how great you think you tuner is and the safeguards incorporated.
Once you get older, you'll start to care less about being the fastest guy on the street and come to the realization that even a excellent handling low 14 second car on the street is plenty quick, fun, and has more than enough power for most every situation.
