Geeeeeeee I would cancel ittttttttt.
Screw the dealer,I am sure he knows he will not get the car because of his allocation.
Get your money back and wait till the spring and get one at invoice off of your dealers lot...
I am sure there are many dealers that will have 2009 RTs when spring rolls around.
And I Know you will get the RT at Invoice if you look a tad and maybe there
will be rebates also..........I would cancel instead of waiting for something that might not come in......
