I bet you cannot wait! I am so jealous!
I had a scout but couldn't find the thread where a detailer had a brand new BMW from the factory, no dealer ship touched it. Still with like the chalk markers on it and some of the plastic protection strips, he then went to town on i, full head to toe clean and protection. That for me would be a proper job.
A dealer will want to wash it and make it look all shiny their way, which won't be a as good as if you or I spent a couple of days detailing it. I have read some horror stories and seen some of the marring and swirl marks left on a brand new car from the dealers.
Are you big into your detailing or new?
I'd personelly not have them touch it and then wash and protect it my self.
