Well your analogy just gave me a chuckle and the topic was so serious I
had to tickle it. (and get Felix involved in the process ) I
think the first mazda rotary was in the RX2 or RX3 which was a little
coupe. It is becoming vague, but I do remember a fello giving me a ride
in one and getting that tiny car almost to 100mph in no time WOW! But I
was thinking of the mazda pickup with the old 1600cc piston engine just
like the ford courier (mazda 1800cc). Pretty good little pickups. I
rebuilt quite a few of them and had fond memories of the rocker arms
with that little ball with the flat spot that rode the valve - many
installers would forget to get the flat down, and after a few miles it
would correct itself... a definite comeback because the lash became
quite large and noisy suddenly. The one annoyance of that engine was
the ratcheting chain tensioner which worked fine, but took a few more
steps to get if the chain dropped while removing the head!

Hey! 145000 miles on a GLC ain't all that much. But I can see the point
in upgrading by then. 

So why didn't the Miata get a rotary? THAT would have been fun! (smog?)
