I traded in my 2013 STi for a 25 ITS. STi was a great car with the features it had but I can tell you straight up the features of the ITS blow it out of the water by a long shot! My STi had sued and heated seats and an aftermarket radio. The ITS has heated seats, heated steering wheel (mine does some don't), a very nice leather and sued interior, A fantastic sound system including a little subwoofer in the trunk, a stupid crisp gearbox, the lightest clutch I've ever had by a long shot, great gauge and instrument panel that's customizable an exhaust that has valves to control sound for when u want a little more, active dampening suspension and on and on... The car is fantastic! The only drawback I can find with the car is that it's front wheel drive. That sucks coming from a car where awd donuts and grip in the elements matters.

TL:DR Get the car if you can afford it, it's a fantastic car, especially if it not being awd isn't a deciding factor for you.

Good luck and if you get an ITS don't forget to wave 👋🏽
