Beauty is very much in the eye of the beholder. To denigrate someone else's design, basically for clicbait, calling it ugly, is an affront to courtesy. Shame on you sir.
Might I suggest you keep your opinions of US car culture and vehicles to wherever you are? First, CONCEPT CARS ARE NOT EVER MEANT FOR PRODUCTION. Second, most of the vehicles in the US produced in the US as we transitioned from war to peace-time production were pre-war designs. IIRC the US did add a bit of hand to ensure that The Third Reich and its Axis partners didn't win WW2. Keep this crap up and some of will start a channel called Stupid Cars from Countries That have folks with Accent that seem to be kinda British Based and start with the Robin...you know, the three-wheeler that Jeremy found could not turn either right or left without falling over.
You say "the Thunderbolt was impractical" a dozen times, but only give 1 example (folding hardtop) of an impracticability or unreliable function. Where's your facts and evidence?
