Ex-police car - buy or avoid???

[2011G6E]

Cop cars used to be treated like crap...regularly serviced crap, but still crap. Back in the early eighties a workmate of mine went to Brisbane to the auctions to buy "a police car" as he heard they were cheap. We said he was mad.
When he came back he proudly showed us his purchase, which he had snapped up for four grand.
We walked out and saw an XE Fairmont Ghia, metallic gold, cloth interior, all the options, power everything, and with only 30,000km on it in two years of use. He said he'd looked at all the XD and XE white police cars, and many of them were pretty sad with high kilometers...a lot less hiding behind bushes with cameras back then and a lot more actual driving around...once known as "police work".
Then he saw a detectives car come up and he couldn't pass it up. The only holes anywhere inside were some small ones on one side of the console where, obviously, the little mount for a radio handset had been fitted.

If you're careful no reason not to buy one.
