Well you acceptable levels are right up at the top right of the sheet.
830 being standard
650 being minimum (the point at which mazda would replace under factory warranty)
But the rpm at 215 is low compared to the 250 it should be so your actual compression will be a tad higher. If I was the one looking to buy this particular rx-8 I would be saving my pennies and expecting to encounter engine fail in the next year or 2 depending of driving style and mileage driven.
Keep in mind you will most likely encounter other needed repairs along the way and they add up fast. Ignition coil, plugs, and wires will run you around $800 bad coils can very quickly kill an engine. And there is a whole list of things that should be addressed on the rx-8 to insure it's longevity. Go through the forum, read, read then read some more, then come back re read it all. There are so many things that can go wrong and so many improvements that can be made over factory.
Way to much to list in this response. Anyway, if you do decide to purchase the rx-8 definatley get more info on the car, the maintenance that was done, the mileage that the engine got replaced and what not, and definitely ask for a reduction in price based on those numbers.
The minimum is 680, but it's getting close to there. 640 at 215rpm is a hair over 680 at 250. I would not pull this trigger unless price takes that into account and you're ready to get a rebuild soonish. Which is fine, it is a good option, you get a fresh engine that you and only you takes care of. The price of the car just has to reflect this.
800 for coils and plugs is you're shopping at the dealer, you can get them for 250ish elsewhere. The advice to read up is good, check the New and Potential Owners thread.

That's very true,I just didn't want him to be surprised at the cost of them if he did go through the dealer. But there are so many options that have better performance and price, like the bhr kit, I've also heard really good things about the sakebomb kit. But if you did go for aftermarket don't go with the cheapest ones you can find, like a 4 pack for $50 the cost savings is not worth the risk, at least in my opinion. I would just go with what loki said and make sure you have an engine priced out, and that the cost is right (low compression can actually be a good negotiation point on an already good priced rx-8, which is what happened to me) then just make sure to get quality coils for the new motor, I wouldn't use the old ones without knowing there history.
