I KNOW I've told this story before (as we wait on Larry to get his stuff back from the machine shop)...

I was working in ATL and living in Birmingham, commuting on the weekends, waiting to sell the Bham house, when the wife calls up on a Thursday and says the dishwasher quit. I was working for a builder and so got a heck of a price on one in ATL. I was driving a Fiat 124 Spider. I tied it on the luggage rack and off I went to Bham in the pouring rain, making the most amazing roostertail with the great big "spoiler" on the back.

So, yes, I think you could get it in the miata, but I don't think the miata will survive the trip intact...
