I’d probably have trouble not modding a car a little bit…
Are you even happy with the WRX? If not, trade it in on a nice easy to maintain DD and pick up a M3 to beat to the ground. I.e., track car, project car, whatever.
Or just something cheaper that you don’t care about when/if it explodes.
It’s really all about driving something you enjoy. Find that and ultimatley do what you want to it…
