Dealership jerking me around

[Cubaboy]

I went in to buy a new 370z (6spd + sports) from my local dealer. Couldn't get a great deal, because they said the car was at another dealership, but I got a decent deal. OTD was about 34k after taxes.

I came in the next day after making the deal to sign the papers and pick up the car. I asked where the car was, and they said "still at the other dealership". I said I didn't feel comfortable signing before I even saw the car (test drove one a few weeks back), but they said they would have the car that evening and to go ahead and sign the papers. They took my trade-in and gave me an 09 Altima Coupe to drive around for the day.

I did (first mistake!) and got a call about 3 hours later saying that they couldn't get it tonight and would have it the next day. Well, today is the next day and the dealership called and asked my second favorite color is...What the hell? They say they "might not be able to get the car from the other dealership". I google'd the VIN, and it's about 2 hours away...

If this dealership doesn't get me the car in the contract, it's void, right? Should I let them find another car and ask for a better deal/incentives? Should I demand my trade-in back, tell them to rip up the contract and just go to the other dealer 2 hours away? It seems like the are royally messing with me at this point....

Help guys!
