The only thing I'd be concerned about with my car is the seats as it's still rego'd as a 4 seater but has fixed back seats in the front. Although I've never let anyone in the back while driving I doubt the cops would have heard that story many times before.
Edit: F**k it, if I get defected it will give me more motivation to keep the car off the road for a while until I get some of my bigger mods done.
