Here in Detroit area, it appears that dealers work differently. I placed my '06 Solstice "order" one year ago - the dealer put me on his "list" and stated that I will be the first order placed when they are able to process orders. Any dealer with some smarts should be glad to start a list and then proceed with ordering when able. Keep in mind each dealer will receive only a few (up to 3 or 4) when production begins and then the wait to fill orders will take place, based on each dealer's allotment (which is tied to dealer size/sales volume).
When the PT Cruiser came out, I ordered one from two different dealers in the Detroit area, one hour apart. Both were 5pd sticks, which took longer to get. The first one arrived in June, 2000 - I drove it all summer and sold it over sticker. The second one (which I still have) did not arrive until September, 2000 (same exact model, color and options). My point: the dealer allotment may determine when yours will arrive, so talk your dealer into taking your "order" or putting you on his list.
