From Craigslist:
This is a 2007 mini cooper s with 98000 miles. The cam chain tensioner backed out of the head and caused it to jump time. Engine turns over but does not run. Possible valve damage. No other issues. 6 speed auto. Inspected until end of November. Price is negotiable.
Listed at pretty much full NADA value. I love the fact that he/she is still cranking the engine to prove it will turn over. If there is valve damage, it is actively getting worse!
