Nice car Lexi. Lexie is my cars's name. :-)
Sorry I can't answer your question. From what you explain, I would think black would look better.
Welcome to LOC. I hope you hang around a while.
35% is legal so I wouldn't go any lower than that. I'd probably stay with 40%. I visited a couple of tint shops and they showed me how the various tints would look. It was helpful.
After 2 ES350's I got a 2013 Audi Q5.
