Nice.
I think I'm going to sell
the '91 Firefly convertible I snagged years ago but haven't gotten around to repairing (needs floors). The unexpected MPGiata windfall supplanted it anyway.
I'm very happy with the Miata's ~50 MPG, not to mention more entertaining driving characteristics & better prospects of holding value vs. ~65 MPG and less of the other things with the Firefly convertible. Even though the Firefly has less than half the kilometers on it as the Miata (110k km = 68k mi. vs. 230k km)
