What I will suggest, to play safe and ensuring you can own the supercar, buy a 2nd evo7 and drives it like 3-5 yrs, maybe keep it or sell it.
I have drove other 2 doors JDM sportscar before, and as usual, regretted, coz it got the looks only, driving position is terrible, tiring, parking is hell!
Just get the E7 or any model of evolution, confirm no regret !
About the RX yes it is 1.3 liter only, but maintenance is like hell! If something wrong with your engine, u can prepare to change the whole engine n wait a few weeks/months for another one from japan which cost alot. IMHO RX7 is not reliable for the money you spend.
With evolution, driving is crispy, very direct n sharp handling, 4 doors to fetch your family or your in-laws, looks decent, ride height n driving sight is perfect. It's a perfect city-going-supercar without drawbacks in any point of view. And also not as noisy as the beasty subaru.
And to be frank, E7 more fuel saving than most other 2doors coupe sports car. And usablity is much better.
