Yes I’ve always found silver to be the best colour at hiding dirt, and black the worst (I had one black car and won’t make that mistake again)! I was keen to get silver this time for that very reason, but the Tucson Ultimate has big plastic wheel arches and sills which I don’t like, and they really stand out on light colours, so we had to go with a colour that ‘masks’ them 😂
I used to wash my cars years ago but life’s too short so, like you, I use a hand car was company. I know that they are usually staffed by illegal immigrants and are fronts for organised crime, but needs must 😂
