Due to recent water shortages I've not washed any of our cars for nearly three months - completely unheard of for me. There was never a hospipe ban in our area, but it would probably have been a bit antisocial to be seen using one. The Z, being white, never appeared to look dirty, just dusty, but today the hose came out and spent a good couple of hours washing and detailing it - what a difference, it has its shine back!
