I'm a big fan of Autoglym stuff, but their car shampoo is a little disappointing compared to most of their products.
It goes back to your car shampoos are subjective comment, but personally have no issues with autoglym bodywork shampoo, and can't see what benefit switching to something likely more expensive would bring. Although it doesn't lather it is very slick and so cleans well with a mitt, don't need to use much and smells great.
