This happens all the time, and is a pet peave of mine, my 2001 E430 was the same way. Get them to fix it!
When you take it back and complain, they will smile, and fix it for you, but not the way you want. "New vehicle prep" is the usual name for the guys who will work your car. When you get it back, it will look fine, but I assure you they will use a glaze.
So, after the second or third wash, you will start to see the mess again. And it will become worse as the oils and fillers wash away. That is what happened to me at Mercedes.
So when you take your car back, insist you go meet the guys who will work on your car, or find name of the manager in new vehicle prep. Go talk to them, let them know that glaze is not an option because it is a short term fix.
I am familiar with parking lots full of Mercedes in Northern Virginia and Coral Gables. The cars sitting in storage areas are absolutely loaded with swirls and scratches. Take a look sometime. Their solution is Mequires glaze (I assume the same stuff Mercedes repackages and sells in the parts shop) before a cars make a trip to the showroom or a customer.
I am sure this happens with other brands, not just Mercedes. I bet new car dealers are the largest volume users of glaze!
I really would go back to the dealer, make sure they know you will not accept a glaze job, and work with them on what they will do. The guys in new car prep and in the body shops are fully capable of using a rotary on the finish and producing a very nice result. You can do this yourself, but I do not think you should. As someone else said, get a perfect car, then learn from here about keeping it nice.
