regards to compression issues you only need ten mins looking at posts on the owners clubs to give you
permanent paranoia regarding compression and engine failures.
The engine is flawed which is why they fitted another oil injector on the last variant of the RX8
If your looking at a rex again i wouldnt buy without having a hot compression test at a specialist, too risky.
I really wanted to love my Rx but the performance didnt warrant the running costs
Saying that at 3k for one now it might be worth the risk , still a lot of car for very little money
