Hahahaha. Thats the way things roll when youn get into detailing. Its a passion thing. For beginners you can buy only the car shampoo and wash the car and dry it. Once you get the feel and you have some additional time, you can start using wax to get that glare. Further start correcting some minor scratches with the rubbing compound. And then comes the alloys/wheels. What I have mentioned in my post above is just the 50% of the product list. Ask @SunnyBoi or @fernandeskaran they might have a cupboard full of detailing products.
