Here's what I got from my dealer
I just received this e-mail after being promised my car this week not more than 1 week ago! Very frustrating!!!
Jeff, bad news first and then good news. According to our inventory sheets your vehicle along with all RX8's were pushed back two weeks to the second week of August. The good news is that today we received our first RX8 and it had the same arrival date as yours. Unfortunately this means that Mazda is not very accurate on their predictions. Hopefully your car is on its way but it still could be a couple of weeks. According to one of our regional reps, there has been transportation issues due to the low ground clearance of the car and getting them on the transports. So keep your fingers crossed and hopefully the next time you hear from me will be to tell you your cars is here. Thanks for your patience
