But plenty of people offered suggetions on how to blow his budget making the A4 faster. I'm curious, why not just put that much money into the S4 to begin with? The price difference was 4k to begin with, so why spend what will almost certainly be more than that catching the A4 up on power, suspension, and everything else the S4 has on it, when you could just put the difference into the S4 to start with? Even if the leftover money after spending 4k extra on the S4 isn't very much, you can still probably chip it and fly away from the A4.

 

Yeah, but a bt a4 is so much more fun to drive!
