At this point of time, in my opinion, it is better to wait for the next gen of civic for turbo RS. No timeline in sight for RS bookings to open, its better to get oriel or grande for a year or two.
Civic RS after being used for a couple of years do face resale value issue. Due the initial bad taste of turbo back in 2016-17 "dudes" and their b l o o d y dealer advisers want used turbo for the price of city.
That is why i think it better to wait for new shape, get it, enjoy it for a good 5 years and sale it to some "Modification" savvy dude to destroy it.
