Having owned quite an extensively modified corolla, and driving it everywhere and anywhere, i never had any issues on where i went, of course Yatala gets shut down, but i was never bothered
I knew the car was fully engineered and legal, other than the atmo BOV, but thats my fault should i get a ticket, to which i have never,
I have pulled up at the lights driven past police, even traffic police, and although the having a full cage was tucked away the rear bars did stand out, never had any isssues, i admit mine was a tidy street car,
I'm currently building a Mk1 Cortina which will be very similar to the corolla, more attitude, and is currently engineered, and have built it within the constraints of engineering limits
I have always said, if your shit is good, you wont have anything to worry about, and i know alot of police officers, and yes they have better things to do, so if your car is presented well, and driven responsibly you will not get hasseled, some are just curious also
So build your car, add personality, and although you might want to impress other enthusiasts, and have that grin of appreciation every drive, just be front up with police/transport, they know who are genuine and others going to waste time, if you get the one officer, shut your mouth, and when put on the spot, take your time on your responses, if you get questioned for taking your time, just advised that you want yourr response to be clear and concise
