I’m sure there used to be a lot more DIY decorated cars when I was growing up (1970’s). With cars, the current trend is to conform. It’s not self expression so much as brand association. Choose the car which conveys your self image and aspirations. Maybe customised Beetles and Morris Minors will make a come back… My first car was a 1964 Land Rover. I did it up and re-sprayed it one summer because I couldn’t afford a newer one. Today, fashion is about choosing a ready made solution. It’s not about experimentation. Necessity IS the mother of invention – currently we’re all too well off to be creative.
