Is it a Series 1 or Series 2? you list both, but they are not the same engine, and can't be directly swapped.
If it is a Series 1 engine, then you need to list if it is a 4port or 6 port. If you are selling all the accessories attached, I believe you also need to list what transmission it was originally paired with.
Compression test of 6.5 is not "good", but "passing". More accurate would be "passing but headed toward failure". At 22,000 miles, I would get concerned with that low of a compression number. OEM factory should be high 6s, if not mid to high 7s. I've seen a factory engine in the high 8s.
If you are going to list any compression numbers though (which would be wise), you should list all 6 compression numbers with the RPM of the engine during the test. I admit it's possible that all 6 facings could have exactly the same compression, but it's gotta be rare. That could be stellar compression at horribly low RPM, or terrible compression with RPM over test spec.

When I had my engine replaced my numbers were in the low 7's and high 6's and they confirmed my engine as needing replacement.

Edited post to clarify some things.
The Mazda Dealership said that my engine is still strong. I apologize for not specifying the RPM in which it was tested with.
Compression rating of 6.5 front n back @ 200 is "good" condition, because avg new factory series I (2004) engines comes out at a avg rating of 6.8 @ 200RPM.
Plus I was able to crank out a lot of power out of that engine, much better than a few of my other friends with the same year RX8.
