I had to park the z outside for 3 days while doing tranny work on the Subaru, after I pulled it in, the G/F asked me if I "apologized" to the car.......
I smiled, and told her I was going to "massage" the z with my microfiber mitt and some shampoo to make up for it
I've had her for just over 3 years, and shes remarkably clean. ALWAYS!
