Rx 8 Revolution

Hello dear engine talk community I’ve been looking for a new car for a long time, but there are far too many and all have advantages and disadvantages… Unfortunately I have to admit that I definitely fall in love with the RX-8 from the interior and the exterior design, but I find the consumption of the circa 11-15 liters relatively high … is this a realistic indication? However, I am very concerned with things like “work city costs” , and the reliability of the engine just the wobble I’m worried. Do the horror stories about extremely expensive repairs? Besides, I saw a RX-8 with an LPG upgrade at the dealer’s store a few days ago, isn’t that very daring with a Wankel engine? or really no problem? How much would you recommend as a KM performance when buying? Would Super Whom someone could share their experience values with the car Ps. I drive about 25-30 km to work a day, most of the highway ..
