The idea of a 60s sports car using the Cobra body (in any size) is tempting, but the tall, narrow wing seems out of place for the era. And why does it have such a high ride height? Is it because it has solid axles (leaf-sprung and/or coil-sprung) front and rear? It makes it look cartoonish and not at all realistic for its time.
In fact, none of the cars you have made so far actually make any sense at all - and they would probably be best described as meme cars. Not just because of extreme quality spam (+15 everywhere is an absolute no-no), but also because of engineering choices that seem like min-maxing to me, with no concessions to realism whatsoever.
