i went for a trip to pick up my doors for my car in vic today and saw a VE unmarked cop car...looked stock as...proper rims, really well hidden lights, they didnt stick up any higher than the dash...i thought it was a commodore driver helping another car till i got up close and saw the lights flashing...around griffith theres a mini van getting around aswell...i havent seen it but aparently its like a kia carnival style car, grey, thats about it...so they are getting more common.
id look for lancers too, ive seen a marked lancer floating around, wouldnt be surprised if they are unmarked next...
EDIT: the best way to spot them is to drive 15kms over the limit and look for blue and red lights lol.
Need some parts for my VH 253:
Green standard steering wheel...Green lower B-pillar covers.
Green sunglasses holder/lower dash bits...Air-con and assorted engine bay parts.
PM with any info.
