Oh, I have one of those car wash freebies. Basically if you get a coating from HSS. Supagard, they'll give you a book voucher with car wash & disinfectant coupons. You can just go there, say you want a car wash and they'll take one coupon from your book.

Tbh I've never used mine, its not like they're not good or anything, its just I prefer washing by my ownself

First service would be 12k km/1year. You can just follow what car tells you. There's an option in the car where u can check when's your service is due

Nah no such thing. Just use a normal one will do. I'm currently using 70mai brand not bad
