Looking to get into an RS as a new car owner

I've been a sport bike junkie my whole life but my knees and elbows are not what they used to be. Im wanting to get a car and from the research im doing this one might be what im looking for. There rare enouoh in the states that I can't test drive one or even sit in one with driving 4 hours. Ill be doing mostly mountain roads like the blue ridge parkway and tail of the dragon.

I wanted to ask other owners if the seat height really that big of a drawback and of there's a way to lower them. Im 5 10 so im on the shorter side but I dont like the idea of feeling high up in a sports car

Also Will the overheating issue while driving hard be a problem. I've read that the oil and coolant temps will throw the car into limp mode. I plan on driving the car very hard and doing some track days, I just want some feedback from owners. Theres a 75k mile 2017 4 hours from me I have my eye on.
