You would think that the new dealerships handling all those brand new expensive cars would offer the highest level of detailing and car care..  But sadly it's the opposite.  I can not stress this enough, but most dealership detailing facilities are very uneducated in the detailing industry, while suffering from lower standards, using the cheapest products (that are often unsafe) and rushing their work.  Their bottom line is quantity over quality.  They're using the same dirty wash brush on every car, swirling the brand new paintwork.   Even fancy "high-end"​ dealerships don't detail correctly or know proper polishing techniques.  Just check out the paint condition on this 2011 Jaguar that was purchased from a high-end BMW dealership in IOWA.  Now check out MY results on that same Jaguar.  Or have a look at this brand new Mercedes C300 purchased from Fargo.  Within the detailing industry, dealership detailing is sadly considered the lowest form of quality.  Here are a couple more used vehicle examples: this '11 Lincoln MKT or this Silverado that had both recently been purchased and "freshly detailed" from dealerships.  So if you want your vehicle done properly and correctly, have it worked on by an educated and reputable detailing shop.  You might pay a little more, but you'll get so much more value out of their work, and you'll have peace of mind knowing your vehicle is in the right hands.  When buying a brand new vehicle, the most educated customers will often not let the dealership touch the vehicle at all, and will instead have the car shipped directly to a high-end detailing facility to have it properly prepped, and properly ceramic coated.
