Having read HC of Ashbourne's letter I wanted to let you know about a fantastic British company called Multimac: www.multimac.co.uk. It manufactures 3-abreast and 4-abreast child seats to fit most cars and that grow with your children from 0 to about 12 years. I've attached some pictures of the one in our Range Rover Evoque, but the same model would fit in a Golf. They're fully crash tested, our insurance company is happy and Multimac even upholstered ours to match the car interior. I couldn't recommend the seating system or the company highly enough to your readers. It really does allow you to safely carry your whole family in the small (or large) car of your choice.
