I am thinking of LEXUS RCF ( Not RC350) for my next daily car. I used to drive very generic sedan.
This time I like to drive a reasonable and comfortable muscle car ( not too harsh) as a daily driving car.
Appreciate any experience and opinion from you. I already looked at M4 and did a test driving. It didn’t work for me. I am late 40.
Unfortunately, No dealer near my residency has RCF. I am considering a customized order through a dealership nearby.

I love muscle car and racing.
Why don’t you try Mustang GT or Camaro SS for your first muscle car?
I’ve never seen any guy drives Lexus RCF.

I do drive Mustang GT for my daily car as well. It’s a very nice and fun car.

RCF is a great car with a naturally aspirated V8. I’ve never seen any guy drives RCF: That’s exactly the reason why the OP should buy it for the uniqueness. Don’t wanna drive cars that everybody drives, right?

Take a look at this youtube https://www.youtube.com/watch?v=ZOqaWmfyd3g&t=1553s

I would rather buy a Ford Mustang Shelby GT500.

I recommend to test drive Dodge Challenger. 6.4L or 6.2L

I recommend challenger too, 6.4
