Just noticed this thread.
You couldn't give me an ex-plod car.
and don't give me any of that guff about maintained regardless of expense or the motorway cars are different, we used to have the plod breakdown contract, which of course included recovering all the broken and crashed plod cars.
Commonest fault was a blown head gasket, they'd just sit there and idle the engine to keep the heaters on, cook the engine, and not give a toss. NOBODY ever checked levels / fluids / tyres, the only gauge checked was the fuel gauge and odometer reading.
Also not at all impressed with their driving skills, one or two rare ones were excellent, most of them made african taxi drivers look like IAD instructors.
I'd rather have an ex pizza delivery moped.
Even plod won't buy ex plod cars, that should tell you something.
