I doubt they'd ping you in a stock KE70. In the case of an on the spot inspection with "old bombs", they'll look for the obvious; bald tyres, frayed seat belts, damaged exterior parts, lights out, blown mufflers (loud exhausts), or general rusted arseholes all over the body of the car.
And of course there are always the defective aftermarket mods, (which today police are well aware of, and take into account) that majority of "old bombs" dont have...
I definitely agree with their intentions though, good on em for targeting older cars, so they should. But i bet the majority of their quota from this super defect blitz wont be old shitboxes.
imports, rice burners, commodores and falcons with large bore loud exhausts, giant f*&^ off fmic's, fiberglass & plastic pig aftermarket bodykits, atmo BOVs, electronic interior wankery, low ride height; and of course all of the stuff I mentioned above = Much less hesitation + easier canary slap.
