Ridiculous price. If you speak to a local detailer, they will apply body protection for much less than that inside and out and do a much better job. To look one up local to yourself, look on detailing world, often they also will do the new car preparation including applying protection for about 3/4 of that price.
At the end of the day realistically it is just polish with a sealant applied, often Audi use Autoglym products which, yes are very good, but the majority of what they charge you is for labour to apply it. Detailers will use products such as Menzerna, Gtechniq or similar appropriate polishes which give better results (IMO).
