I bet it does I've never come across a car that didn't need claying, apart from one that has just been done.

To check whether you need it, wash and dry the car. Then put your hand in a plastic sandwich bag and run it over the paint - unless it feels perfectly flawless like glass everywhere, it needs claying - you won't be able to see these contaminants, only feel them Trust me on the clay - people are often sceptical when they've not tried it before, and then amazed by what it pulls off, and how much better the finish is once it's been re polished after (as the polish works much better after a clay)
