Since there is already a thread running on, "Achingly, Timelessly Gorgeous" I thought it might be interesting to look at the other end of the scale. So here's my pick:
* Voisin C6 Laboratoire (though I do find it compelling to look at)
* Ligier JS.5 'teapot'
* Ensign N179
* Cadillac 'Le Monstre'
* Nissan GTR LM
* Daytona Prototypes Gen 1, 2 and 3 (but not including the Gen 3 Corvette, which bizarrely belongs in the other thread)
* Mosler Raptor
* Rondeau M482
* F1 clown cars from the 'protuberance' era (2014-ish?)
* McLaren Senna.
