I leakdown my engine every time I have it out of the car (about every year) - readings are typically very low leakage (I'm lucky I don't believe the valve guides have every been changed). However, last time I saw a bad reading on one cylinder I slightly freaked until I smacked the valves with a rubber mallet (had the valve covers off for the adjust) and it immediately held pressure. I think it just got a piece of carbon under a valve, maybe during the spark plug removal...
Just something to consider, since you already have a ticket - go and drive the car (hard) and see how the engine feels - it should be fun, peppy and put a smile on your face. No smile, no purchase.
I got my car back in 1993, before widespread internet and these great forums - no PPI, I just went and visually inspected (did put it on a lift) and drove mine and was SOLD!
