I looked at a couple of ex highway patrol cars for the missus. 2007-8 sv6, 160 odd thousand kms, very good service history --- anything that needs doing gets done, upgraded suspension, brakes and some are chipped. Other than a few wee cosmetic things that could be tidied up easily, they were a good buy in my opinion. Usually selling between $11-15K. Car dealers usually out-bid you, tidy them up and re-sell them for $20K plus.
