Wait, I'm not even sure I follow the logic trail of OP's statement that if they were gonna spend the money on a 2SS (roughly $46K) they decided to just go full-boat up to an RC-F which base prices at $63K but after clicking a few worthy options you're easily at $70K. That's a $24K swing on a notion of "meh we've gone this far...".
That being written, on a purely car enthusiast level, RC-F would've been my last choice out of all of those...way too heavy compared to the competition and the motor is weak (as well as too peaky) for that price range. In my eyes, they built it to beat the E92 M3 but didn't consider that the paradigm would shift beyond what they were shooting for before it was too late.
In that loftier ($75K to $85K) price range I have it:
1. New Mercedes C63 AMG Coupe (it is incoming)
2. Cadillac ATS-V
3. BMW M4
4. Audi S5 (until they bring back the RS but even here you'd need to take it to Stage 2 which brings the total to about $70K all-in)
5. Lexus RC-F
It's pretty though, I'm on board there. Also Toyota/Lexus reliability is on-point. But if you have enough money to buy a car at that level you have enough money to afford the extended warranty. Hell, my current car is a level below that car and I was easily able to do extended warranty plus maintenance plan.
