There is a further factor working against the Commodore: the high cost of tyre replacement and the frequency with which they need to be replaced.
The cost of replacing the 18-inch tyres on the Commodore SS is close to $2000 per set and because of their low profile and high grip level they wear out more quickly.
What that doesn't take into account is how the cars are driven, as well as the difference in the suspension setup. I've seen quite a few commy police cars frying the rear bags coming out of side streets or at a set of traffic lights. I'm not saying that they don't do this in Falcon cop cars too, just that I havn't seen it. Also, sadly, the majority of young police, if they have any interest in motorsport, are probably holden fans, and so are probably more likely to give the common-doors a thrashing.
My 2 cents worth, feel free to demand change.
