Upgrade my car or trade it in?

I'm currently driving a Honda Civic 2016 Lx, and I recently got really into modification on cars. If I do decide to buy the car right after my leash, should I take the time to mod it out, like adding new exhaust, wheel, hid lighting, or just save up just to buy a kinda of a sport car like Lexus, vw, or even a old wrx and modify those? I'm just looking for opinion.

Trade it in.
