OP, I would suggest scheduling a session (or accepting delivery) at the Experience Center in either Atlanta or Los Angeles.
The Experience Center is tons of fun. There's an ice simulator, windy road coarse, launch control drag strip, and more.
You can experience the limits of the car in a controlled environment and not damage your vehicle, risk anyone's safety, or get arrested for seriously violating traffic laws. 😊
I did so many drifts, donuts, spins, etc. that I was slightly nauseous before the 1 hour mark. I left the Experience Center confident that I could adequately handle my vehicle in pretty much any road or weather situation.
The 2019 Boxster is my first sports car and first Porsche (only my 2nd vehicle).
I am a relatively young Porsche owner like you, and I found the Experience Center Delivery helpful to build my confidence with the vehicle, explain the features/controls, and to get my experience more "up to speed" with some of these Porsche veterans. 😉😉😉
You can choose to drive the car like a grandma or like a maniac. Whichever way you chose to drive the 718, it is a complete blast.
Congratulations and enjoy!
