How long should I wait once I take delivery of my M before I polish and wax her? Or even clay bar, polish, seal, and wax her?

Hopefully the dealer will do a good job cleaning the car before delivery. Anyway, the paint should be fully cured so there is no concern about that. I'd do it as soon as I could tear myslef away from the driver's seat. ;)

You can do it right away. At our dealership, (LOL SATURN) if you decide to do a full detail, we put paint protection and wax over the paint. BMW paint should be the same

You can detail right away, as a matter of fact, I'd recommend not letting the dealership touch it at ALL. Take the plastic wrap off yourself, that way, you know they're not going to swirl the car. Factory paint is backed before any of the plastics go on, so it's fully cured when it arrives. Remember, the manufacture date is when the car is completely together, not when it's painted. I'll bet your car is been painted at least 90 days; you can clay, polish, seal right away.

Yeah, i wouldn't let the dealership touch my new car. Once heard of someone taking delivery of their new Black Rx-8, walked outside and the salesman is "cleaning" the car with a dry duster. :shifty Ruined the paint on the hood.

I'll just add that I took my car in for a coolant flush and oil change the other day. The dealer was kind enough to wash the car. When I got in it I realized that the car was dirtier than before they washed it. There were dried streaks of dirt on the windshield where they used a rag to wipe it.

Now this wasn't a new car prep, just a quick courtesy wash. Most people would have been pleased with the service, but in the future I'll ask them not to wash the car.

My local dealer just got the autobutler system, but they still know not to wash my car. It's good to have all the techs as well as the service writer know not to wash my car when she goes in for service.

I would do it asap. You shouldn't really need clay or polish since the paint is brand new but I'd wash it, seal it, and put 2 coats of wax on it. :)

Actually, depending on how the car was delivered, it may need to be clayed. Most cars within the US are shipped at some point by rail. Alot of what needs to be pulled off new cars is rail dust. The good news is on new BMW's, the plastic covers ALOT of the paint, so there's minimal areas that would need to be clayed....IIRC, it's the back half of the hood, top, front half of the trunk, rear/front quarter panels; all other surfaces are covered in plastic.
