Wow what a day! within acout 20 minutes, the mail lady delivered my new AMG center caps, FedEX Ground delivered my 2009 SL550 wheels, UPS dropped off some new hub centric wheel spacers, and THEN DHL delivered my STAR Diagnostic System! If any of you would love to have the $30,000. STAR System used by the dealers and pay under a $1,000 let me know. Kanzus got me in touch with a great company that sell the cloned system. I bought the Compact 3 system for $774 which came is everything but the required IBM T-30 laptop. I bought the laptop in like new condition on Ebay. I am jnst now starting to play with it in simulation mode and am going to see if it will work on a Crossfire by selecting R170 SLK320. Here is what all you get (see picture) Cables to work on any MB, hard disk with factory software for IBM T-30, Multiplexer, and even a nice locking hard case.
