Unfortunately for what ever reason, the young p platers buy these 90's 2000's era Commodores and yes being young modify them as we all did, and then proceed to drive a little crazy...This then brings them to the attention to the coppers and what happens happens.
Back years ago, with us elderly members now, we would modify our cars, maybe act like idiots and generally we would get the boot up the ass from the copper and told to pull our heads in...Or at the very least, the copper waving the finger at us to give us the hint, pull your head in pal before we pull it in for you
Now that sort of behavour is frowned upon by the coppers, so they see a modified car, which we saw as acceptible, deem it to be unacceptible and tend to come down hard on the driver. Very rarely do they give that nasty finger wave....They let the pen do the talking
So the best course of action to save drawing any unwanted attention is, keep the car tidy, stock looking, stock sounding and a copper won't look twice because this era Commodore is the "go to" modifying p plater style car
