Welcome! Only Green Envy ST I've seen in the wild was in Boerne, TX North of San Antonio a couple years ago. I've test driven two other green ones before I bought my car. It is an excellent color. I'm sad it's not more common and it would have been my choice but orange is my favorite color so I was really torn. Ultimately I had to go orange but I still kinda want that green because people mistake my orange with red way too often. Bright colors go great on these cars though.
Front plates are a law, but cops really don't cite you for it unless they want a reason to pull you over or they pull you over for something else and add that on. That being said, I'd rather just deal with the front plate on the car than deal with a cop pulling me over for no front plate. The plate on the factory front bracket actually doesn't block the intercooler or the radiator. It comes up on the grille, but if you look the bottom half of the grille is blocked off anyway because the crash bar is right behind it.
I'm up in DFW, but I come down to SA a couple times a year to see my parents. I hate the Spring weather here. Glad I have a carport, but sadly it doesn't protect my car when I'm not at home. Got out of last years weather with a single hail dent on the roof. Sunday we had hail in areas that were baseball sized. I didn't even get any rain but someone I know posted about a friend's car that got obliterated by the hail about 15 mins North of me. And then Tuesday we had Tornado warnings overnight with high winds and trees and limbs that fell over. My co-worker posted a picture of a tree that fell on some cars at his apartment.
