Let's solve this.
Still missing:
#7 - Is it a 3-wheeler? Nope, 4 firmly planted wheels.
#9 - Japanese concept? Also decidedly not.
#10 - Delage D8? Not a Delage.
#12 - German? Not German, but close
#16 - A manufacturer's prototype or an independant's (Sbarro-Rinspeed-etc..) Manufacturer's prototype is correct.
#20 - American? Nyet.
#26 - Japanes? Nee.
#29 - German? Nein.
#30 - German? Ne.
#31 - One-off? I believe so
Let's change strategy:
#10 - Voisin C15 Roadster Saliot Not Voisin either.
I think that number #31 is a Lancia Aerodinamica by Zagato See discussion at the bottom of this page...
#20 - Thank to Allemano I can say that is a JAG Combined with the Gurgel answer below, yes that is correct!
#31 - Should be the Lancia Aprilia by Viotti See discussion at the bottom of this page...
I know there is a discussion about this Aprilia in the expert section, but since I'm not allowed to post there....
This pic cames from an opera dedicated to the Lancia Story: 47 booklets. This one comes from the booklet dedicated to the Lancia Aprilia Derivate...they are all there, Zagato, Pininfarina and others.
(Of course Joćo get the point, because he found the car.) See discussion at the bottom of this page...
Let's solve this puzzle!
Number #16 it's the 2001 Chevrolet Celta Spyder (Again!) Yes that is correct!
DHoffmann was last active in August.
Hope he's alright! Thanks for the concern
31. Porsche 356 on a VW Beetle As discussed by others, no it isn't.
So for 31 most of the details are there, but the name I have of the coachbuilder is different. I have no source for my image anymore, it does not seem to appear on google images anymore either. I do see that there is a single source for the Zagato name, with the image posted by Joao and PJ featuring there. The Viotti name adds some images of scale models but the same image already posted is the only one of the real car.
I'm thus a little uncertain how to proceed. If my source is correct, I don't think I can give the point? If viotti is correct does the point go to PJ despite the base of the car being guessed earlier by Joao? Anyone with thoughts on this?
So currently still unsolved are:
#7, #9, #10, #12, #26, #29 and #30 (sort of #31?)
