This looks very clean, although I would check the flooring under the installed aftermarket floor tiles. The wood floor is easier to keep clean.
As a reference point, I purchased a used 2012 TC650 in December last year, and paid $12,000. It included all the above standard options you list, including the scissor steps and the fast guns. Mine also came with a full camper cover (although I don't think I will ever use that).
Before we purchased this used, we also looked at new, but it worked out about $18k once you figure the extras. The local dealer advised removing the plastic bed liner, which we did, and installed a Line-X spray-in together with a rubber mat.
