Buycaruk.com is a car valuation site like webuyanycar.com. A user enters their number plate, a mileage estimate and in return gets a valuation for their vehicle.
These types of sites are used by all groups of people from the tech savvy to the not so tech savvy. This means the design needs to get 'to the point'. Users need to know what to do and how to progress without understanding your specific navigation.
It's imperative they don't lose interest or feel out of their depth and move on to another simpler site. We feel we've achieved this with a simple intuitive responsive design.
