My mistake. I meant the Chevy Monza. The Tornado [sic] was, well, okay ...

The first couple of years out, the Toronado didn't get a change in a few gaskets to allow it to use fuel additives for "cold weather starting" (i.e methane/alcohol?) that were just beginning to appear at higher concentrations in cold parts of the country. One acquaintance went through three carburetor rebuilds the first year, before someone told him what brands of gasoline not to put in it. (The brand warnings varied with location.)

Once he got past that, he pretended he thought it was okay.
