1958 wasn’t the best year for GM style-wise. But today 58’s in any condition, especially the Chevy Impalas and Pontiac Bonnevilles are worth big $$$.
yeah, all “one year only” body styles. Chevrolet was working on a 3 year cycle back then, and the ‘58 body styling was to be carried on into ‘59 and ‘60 with minor revisions. But then GM got a look at the Virgil Exner designed ‘58 chrysler products and decided that they would accelerate their next generation designs: longer, lower, wider- less chrome, subtler styling. So all the ‘58 designs were for just that year only.
