My 32 was my daily for nearly 3 years, through various levels of modification.. got pulled over 3 times.. first by D's because I gave it a bit of welly on to Leach Hwy, pulled me over to tell me to take it easy, popped bonnet, made me rev engine etc, cya on your way.
Second time, had just put 3L in, then had to take car to suspension shop, picked it up, hadn't sorted bonnet not shutting properly (passenger side sat up about 4", was only on the safety latch). Had a new 3L and new suspension setup, grabbed 2nd a bit too vigourously across an intersection on the way home. Cops were going other way, didn't see me but heard it, took a while to catch up, pulled me over, asked me to pop bonnet.. I asked if they had anything to cut the cable tie.. it went downhill pretty quickly from there.. drove home with a yellow sticker
Third time, heading in to work in town on Xmas eve, cops in paddy wagon saw wrong colour rego sticker (was 2 days late ), cops went over my car, pop bonnet, ask for permits etc, had a chat about the local indigenous population, fine for not displaying current rego sticker, cya on your way.
In the Stagea, never been pulled over other than going through booze busses (escaped without notice). Oh did get pulled over at like 5am one morning when heading to a paintball tournament, I had just pulled out of my driveway and headed up the adjacent street. I could see high beams coming down my street and said to the mrs, I bet that's cops. They turn to follow me, lit me up, sat behind for a minute then pulled round next to me and said sorry mate, just got some reports of dodgy people in the area. Good to see they were doing their job diligently
I have found that if your car isn't a R.I.C.E. mobile and you're not driving like a cockhead, they won't bother you. I think being older with a beard helps too
