I'm thinking about a purchase of an used Mazda RX-8. I didn't determine yet will I buy version with 192 or 231 HP, ph1. I'm interested in difference in consumption of this two versions. Which gives more bang for a buck?

 

You should start here and read about the different versions - work out (for yourself) what's best for you.

My opinion doesn't matter.

But I'm sure they both use lots'o'gas....

 

Ok. Are there any certain factory problems with engine or any other part of the car?
