If you do it properly? Takes me at least an hour to wash it, and that's without doing the wheels properly.I'm trying to think how I'd spend an hour a week caring for my CC.
I mean washing it .. 15 minutes.
That about covers the hoovering. Then if you clean the leather, you can add another 1/2 hour onto that. Clean the windows, polish hoops & other bits and you're looking at well over an hour for the inside...Cleaning the interior (every week?) -- 15 minutes.
