Before I bought the 86 my car was an '05 RX8. Heaps of issues, cost me quite a lot. Did I love every second of it? Yep. Would I do it again? Probably not.

Engine blowing isn't quite as big an issue as it is made out to be, but my fuel would run around 20L/100kms on average. It's a rewarding car to drive, teaches you a lot, but then so is/does the 86.

Any savings you make by buying a cheaper RX8 (vs 86/BRZ) will be eaten up in fuel and misc other stuff. Drive both, and make whatever choice feels right - in a lot of ways these cars are incredibly similar.
