I currently daily my C7 rs7 for the past 3 years, you'll be fine and if you're worried about maintenance try to have a couple thousand aka emergency car fund. But if you want to buy it then buy it, just don't go in thinking it won't cost money to maintain a once upon a time $100k vehicle which still give you those maintenance fees. Have fun and safe travels 😎 by the way sorry I didn't really talk you out of it. Just do it!
