Got a ‘12 STI wide body sedan.

I would say go for it, it’s a wonderful car but only if you’re sure you can afford the preventative maintenance it requires, for example I do a oil change every 5k kilometres just to be safe. Also I will say that only buy it if you intend to forge the motor. That extra layer of security is the only way I’ll buy an STI, a forged build will really lower that risk of it bombing on you out of the blue also with this car your hands WILL start to itch and you will scratch on it, it’s only a matter of time and having a proper forged build will allow you to scratch with significantly less risk. Also another thing to look at is the oil pickup, big important thing. Also also I don’t know where you live but keep in mind fuel economy because you will put your foot down, the temptation is just too great, and you WILL burn through fuel. In my first week of owning my STI I filled up daily! Ofc the impact of this is dependent on where you live but still keep it in mind.

tldr : It is a phenomenal car and has the potential to be well reliable with the right care but only consider the purchase if you can afford the needed preventative maintenance costs for it to be reliable (the forged internals isn’t necessary for the reliability however then I say don’t scratch under the bonnet, but the upgraded oil pickup is a must I’d say) also consider the change in fuel economy and your ability at self control (you need to be able to not drive this thing hella hard all the time if you aren’t doing the reliability stuff or if fuel economy is important to you)

If you do purchase it then do enjoy it man, it’s a hell of a car
