Don't assume that it's only the engine or transmission that might suffer in police use.
One of my responsibilities whilst working with the police during my last year's was oversighting the maintenance and repair costs of our command's fleet.
We received a bill one day for repairs to a HWP car. The repairs included transmission Cross member and lower rear control arm and various other chassis/suspension components. I can't recall the cost but it was well over a grand just for parts.
I contacted the dealer to clarify the details and they still had the crossmember. I picked it up and examined it. It was alloy and totally lunched. We made inquiries from the HWP sergeant who told me the car had been damaged during a pursuit.
The HWP car was parked in a side street. A car drove through an RBT site without stopping. The Police took off after him, making a hard RH turn to do so from the side street. He had accelerated so hard as he turned that he veered across two lanes and over the median strip, screwing a number of critical and expensive components in the process, but continuing the pursuit.
It wasn't the only time we had incidents like this. Sure, they get fixed and regularly serviced, but they get flogged by some uniformed tools, too.
