There is an engine. Is it the right engine? Many a micro has ex Invacar Villiers supplied, but they do differ in many and odd ways to the more unusual car installations. Like the blower being on the wrong side of the engine.
It has plates, and a nice number, but has it documentation to go with it. If so registration is simple. If not it will be given an age related number. Well unless one of the magicians has it, there are ways and means. Hopefully the chassis plate is there and not removed for cloning.
To my mind this car, in the light of achieved prices of restored machines, is probably now cheap! 30 years ago you would not have got £80 for it!
I like the idea of a peach coloured Scootacar. Trouble is a peach has a very large nut in the centre.
No doubt Stephen will have info on this car.
