Bro, I own a RX8 2007 with rotary engine. You are only right about the fuel economy.
Get your other facts straight.. I did all the suspension work. Brake pads ( 8000 Rs for both pairs), Engine mounts ( 12000 Rs). Oil change is every 3000km and i only add a little quarter to make it run to 3000km. Brake pads dont wear out if your brake pins are working fine.. NOT AT ALL Need to fix oil with fuel. thats a stupid thing to do to ruin the engine.
And lastly, i drive RX8 daily because only those should buy who can afford the petrol mileage. Others stay away and drive their corollas. lols
