What car care products do you use?

Washing one's car is a chore to most. But to me, I take great pride in washing and detailing my vehicles. Though I have never really taken pride in what I use to wash them. I usually just grab whatever is in the cupboard, often purchased by someone else. 

Now owning my old classic mk1 Escort I want to look after her original paint and preserve her history, and of course make sure the Silvia is always looking her best now she has her new front bar. So I looked into different products and what's around for a reasonable price and easy to access. Well let me tell you there is a lot of products on the market! Too many to choose from to be honest, so I'm asking you what you use, What you recommend and why? 

I'm looking for something that obviously works, preferably Australian and of course smells good...
