Once again, my poor foreign language skills are revealed.
This car is an ABC Tricar. And translating from the French:
L' ABC Tricar was a " cycle car" constituted of the front cradle, the shortened platform and the engine of the Minis. Of course it n' there qu' had; a wheel with l' back. Weighing 500 kg, it reached 135 kmh equipped d' an engine 850 DC, and 150 kmh with one 998 DC. This model was manufactured with 25 specimens, of 1969 to 1973 per Auto Bodycraft.
If that doesn't make any sense to you -- go to the MINI Planete site and translate it yourself.
