OT: Mazda RX7 FC3S

[a112]

I know this is not so related to hachi,but it's related to technical,if it's need to be moved,just move it where it belongs.I saw some of you guys own FC.And i always hear that engine dies and simmilar things,but is it engine's or the owner's fault?
Is wankel rotary durable when you regulary maintain oil level and maintain neccesary stuff.
Since recently,i started to admire a wankel engine as a master piece but with a few flaws,just want to know if you can avoid that problems.
And has anybody had expirience with rebuilding a rotary engine,is it complicated,or is it a bit simplier than a otto engine.
And my last question is,what do you really think about the car.
Thank you in advance,i don't have intensions of buying car (yet ) i'm just curious.
