Starts right up, idles smooth, drives fine (we bought it 200 miles away,
drove it home no problem, 21 mpg @ 75 indicated-- 70 per GPS), when
accelerating from 65 to 75 while in fifth, floored takes a measurable amount
of time, a downshift to forth makes a huge difference.

She tacs out to the beep just fine, but I can eat lunch while waiting for it
to happen. :)

It's been 3.5 years since I drove my old convertible, the one I sold when I
bought my RX8, MAYBE it's that I'm expecting too much and am comparing it
too much to the Renesis... which I'm trying hard not to.

Thanks!
