I just placed an order for a gl550. I had been bugging the dealership to let me know if the 550 was coming out anytime soon (since I had a 450 on order but did not want to take delivery then have the 550 come out 2 months later). Well, they called me over the weekend to let me know they had just got an allocation for 2 gl550's. The interesting thing is that they still do not show a invoice price for the vehicle (It kinda felt a little strange ordering a vehicle without knowing the price!). There are very few options you can order (keyless go, I-pod integration, rear sear entertainment, etc), so I assume it comes with most of the major options. There are also two more color options, a verde dark green and a ? taupe color. The build complete date is suppossed to be early July. I'll let you guys know if I get any more info.
