Lacks taper in plan.
I sometimes dream of other cars' details morphed onto my ideal, the 4-passenger rear-engined Volhart Saggitta V2 from 1947. In this case it would be the tail end of the 1962 El Tiburon.
Let's see — Tiburon (El Shark) tail end, Talbot-Lago windshield fillet, Subaru SVX side windows and an active wing between the front pontoon fenders. 21st century lamps and mirrors. That oughta do it.
