Porsche Car Care Products: Question & Comment

[TVC15]

After having my new triple black 05 Box for two weeks, it's time to wash it.

I read in the Porsche manual about their car care products (soap, etc.) and because they said it was important to wash the alloy wheels with a soap with the correct pH, I figured I'd use the Porsche product. (I have also been reading the thread here about other products.)

And, needing oil, I decided to visit the local dealership (Beverly Hills). Yikes! The service people were rude, unhelpful, had no idea about Porsche cleaning products, and didn't even have the oil. The attitude of staff and condition of the dirty, crowded and run-down facility compared unfavorably with my experience at a post office in Soviet-era Bucharest.

Then went to Downtown LA dealership: The building was even rattier, and the guy showed me a service kit in a suitcase, but knew nothing about the products or their availablity for purchase separately. At least they had the oil.

My question: I'm wondering if the Porsche products are worth tracking down? If not, how do i know another wheel soap has the correct pH for the metal alloy?

I must also comment that this experience in the Service/Parts dept. of two dealerships in what must be one of Porsche's major North American markets is shocking. I was expecting from Porsche something comparable--in facilities and staff knowledge--to my experiences with MBZ and Lexus facilties.

I apologize for the long post, but I'm just stunned at the dramatic disconnect between Porsche's product/image and the actual experience.
