Thanks Hugo! I actually bought it down in Newport at Aquidneck/Mazda of Newport/Autocenter...whatever name they go by. They offered the best deal on the '05 and it was the color I wanted.
We worried about the same thing, but we figured if worse comes to worse, the resale is awesome so I don't ever anticipate being upside down on it. We could always sell it in a pinch. Mazdas offering some good deals on the RX8, if you can get past the mpg and oil consumption.
Good to hear from you!
