Well I must admit that all my vehicle must be spotless inside and out. I even go a step additional and detail the undercarriage of all of them too. Frame, springs, you name it, it must be in clean of dirt and rust or I am not happy. This is me, and I would never expect anyone else to clean and polish like me. That being said, I have never had any issues selling my vehicles. Usually my neighbors grab them up as they still look like they came off the showroom floor. Now when I got the Montana, boy I had a lot of work to do. The undercarriage had a some rust and all the black pipe and fittings were not painted. Well guess what, the bottom side is all detailed and looks fantastic. I like it, but a lot of hours on my back to make it happen. Was it necessary? no, but it is the way I take care of my stuff. Our Montana has already been waxed, roof cleaned,(was not white when I got it.)and just detailed before I shut it down for the winter. I wash it usually once or twice a month, as the road, gets it quite dirty. My SOB was taken care of the same way, for 10 years of ownership, and if you didn't know it was 10 years old and pulled for 50,000 miles you would have never known it. Kind of scary if I think about the many, many, hours I spend on all my vehicles, but to me, it is worth it. It makes me happy. Just a side note, going through this routine, I do find many items that need to be addressed, or problems could/would arrive later during our travels. I believe this is one factor of why I have so few issues with my stuff while on the road.
