Should I replace my 370z with an STI?

No don't. You're gonna be a SSUSusuuuu--suuuuu-baaa----ruuuu-UUUU driver. You're gonna be the type to switch out of the slow lane only to drive side-by-side with the driver in front of you, slap on bumper stickers about I <3 Earth and some extremist liberal stuff, inexplicably have a bike rack on your car that you never use, take full stops at intersections on hills while people driving manual Z's behind you are left to suffer, eat pistachios, obsessively watch the Discovery Channel, keep the radio set to NPR, have an "emergency poncho" in the back seat, never take more than one passenger, flip the car over at some point, drive into a lake, drink kale smoothies, never take showers, pour milk before the cereal, don't even the drink after finishing the cereal, all this stuff:

Trust me, you don't want to be a goofy Subaru driver, ever.
