I bought my '17 SS with about 30min tops prior of manual experience. Drove it right home myself and even got stuck in bumper to bumper traffic on the way home.
The clutch and shifter are so smooth and easy to use in this car. It also helps having all that torque to get ya going. The first 2 months were a bit nerve wracking and frustrating at times, trying to learn the car itself and how to drive a manual in general. It did come pretty natural to me tho I must admit. Mind you I was driving an '03 4 cyl. automatic Honda Accord prior to this car lol.
What helped me the most was driving later in the day when not many people were on the road, and keeping my music down so I could listen to the engine as best as I can. Practice, practice, PRACTICE! Take your time and take it slow. Like everyone else usually says, once you have 1st gear down it's all easy after that.
I'm 6 months and almost 4000 miles into ownership now and driving this car is a total breeze. I can hop in and go without a thought and I absolutely love it! I actually prefer to drive a manual now. I cannot stand having to drive my old Honda or borrowing my moms car from time to time.
I would absolutely do it again if given the chance, and my next car will be a manual for sure. I don't regret a single thing
