I purchased a 2011 RX-8 with 16k miles 2 days ago, and have 3 days to take it back. I did not get a compression test done, but the engine core warranty has about 5 years and 4 months left, and power train has 2 years 4 months. Everything feels very solid, but now I'm wondering if I should get a compression test done, and if bad results would be a deal breaker? Keep in mind, I'm 100% fine with the cost of replacing the engine under warranty.

 

I wouldn't be concerned with a compression test for that low mileage on a Series2. I'd probably do one anyway just to get the information of where I bought it at, but I wouldn't have any concern about having it come up bad.

 

You should've did it before you bought it, but at least you know it will be covered by warranty for years to come...good luck!
