There are plenty of Mazda rotary engines around. There are adaptor kits around
to put them into plenty of different cars. (even chevrolets) There are plenty of
rebuilders around.
In the original Fast/Furious, Dom Toretto raced a Mazda rotary and kicked butt.
Rotarys don't get great mileage.
At Sebring a few of the rotarys caught fire.....
not a good idea to pit next to them.
