Some places that I have found that will work on the grey-market 450s are:
2855 S Broadway
Englewood, CO 80113
Specifically talk to the services manager and try to come in the back way where the up-front sales staff can't see you. Also, if you've been following the National Rally thread in the SCOA Members only forum, someone is trying to organize a caravan for west-coast attendees to meet up in Denver and caravan down to Kansas City. Smart Center Denver would love to see people drop in and say hi.

John is willing to work on and fix anything. They have a grey-market Benz G Wagon and usually there is at least one 280SL Pagoda top in there.
I use them for anything A/C and engine related. They do not do tires and brakes. For that they recommended me to the next place.

They have swapped out my winter and summer tires. I have an appointment for Monday 2 August 2009 to have the front rotors and pads replaced with EBC rotors and pads. Have had great experiences with my HHR there as well. However, I am thinking about trying a new shop for the brakes on my 450, the next one listed:
Atlanta Smart Car Service and Repair + Decatur, G
500 Dekalb Industrial Way
I called them today (31 July 2009) to see if they would work on my grey-market 450, if they guarantee their work, etc. So far I like what I hear. Of course the ultimate determinant is what they do, not what they say.
If I have them install my brakes, I will update that information here.
Anyone else have any other shops they've had great experiences with? Midn sharing that information?
And if you're looking for a shop, try Mercedes-Benz Repair Shops - Find a Mercedes Mechanic | BenzShops.com
to find a list of independent MB repair shops near you. Then just start calling each one.
Thats how I found Specialty Repair.
