Welcome! I know a friend who owns the 2016 California T model. The nerd always tells me how he always puts in elbow grease with so many products to make his baby shine. Based on my constant conversation with the friend in question, you could consider using custom touches like carbon fiber accents or a unique color scheme to complement your car’s finish. I however have a Mercedes and my way of maintaining is having quarterly checkup lol at a local mechanic. Its in Mississauga called Right tech...Sometimes local mechanics are best price friendly and more flexible
