Depends what your end goal is. Do you want performance, looks, sound?
First thing i did was a ceramic tint (because Texas), tune, then wheels and tires, then suspension. Then it snowballed from there.
But my priority is performance, then very little of looks (I'm good with just nicer wheels) & didn't care about sound i.e. prefer a quiet car.
That being said, before all that, is take care of suction pump recall if you have it. You can check your vin. Also start saving up for water pump for when it starts leaking.
