^ You have shit on the WRX STI... those things are AWD and will jump off the line like nothing while your wheels are spinning. Trust me, the local subi/mazda dealership brought a stock STI to the drag races here and it was killing cars left and right because it could just jump off the line unlike many other cars there. It was the same with a twin-turbo talon and a VW GTI VR6 (FWD, weight from the engine and not sitting in the rubber patches).
Mustangs are a fun car to drive, my friend has a '89 with a 5.0L and it was awesome, but for practicality-sake I'd take a WRX STI, a 1.8T VW/Audi, or something else of the like. 'least now you can get a diesel jetta or something for the winter... and when you can't afford to put gas into the Mustang.
But yeah, if you truly want to experience speed, get a ride in a drag car. My friend and his dad race their '69 Chevelle SS... it's got a bored-out 427 with so many other goodies (MSD ignition, work the timing from inside the car), and runinng on drag slicks with the exhaust coming out in front of your feet... now that's an experience, the thing is around 550hp with torque that had me sucked back into my seat hard.
