New (to me) 2023 Bolt!

I posted recently about getting a 2021 but this one had less miles and only $1,000 more for two years newer. I also missed that the 2021 was a repo. Love it so far. Level 1 charging is enough for now but I’m working on where to place the 14-50 plug in my garage. Also, what are your experiences with using an 14-50 extension cord if I need to change my charger’s placement?
