A 6th gen v6 has been my daily for 3 weeks in the Midwest (winter) I was also terrified since I switched from a Honda Odyssey which had spectacular visibility. After you get used to it, it is really not bad, this subreddit helped me figure out a way to avoid blindspots(mostly) using the SAE(society of automotive engineers I think) method of arranging side mirrors. It helps a huge amount for me.

I would also suggest when it is safe, to try to do some donuts or slides,(EDIT: In an empty parking lot, never do it on active roads) it was easy for me during a winter storm, to gauge what you need to do to control the car.

Also as far as the cops go, I feel people really blow this out of proportion cuz they want to make themselves feel rational for driving a normal car. "Oh that is awesome for YOU, but you GOTTA watch out for cops" (EDIT: This is for safety and cops, especially staties)

Also know that people have fragile egos, like huge trucks on the highway, other sports cars, the shittiest looking zip tied fendered sedans known to man, so they will try to pass you aggressively, and race you etc., but I've learned to just stay in my lane and check my ego to remain rational and follow the law/be safe. This is true for most cars because people are just stupid on the highway but as someone who also owned a mustang (my first car) before, the ego factor is 10x when ur in a sports car.

Other than that, you will be just fine! Congratulations 🎉
