Not so much if it is stolen but, lets see
States its a 1964 with a B reg, that bit is right
OK, B reg is 1964 but, from the pictures the vehicle is obviously a Series 3 that didn't come
onto the market in 1971
The bulkhead + everything attached to it inside and out is Ser 3, the front wings are Ser 3,
the rear tub is Series 3, apart from the early lights in grill panel I wouldnt be surprised if it was
ALL Series 3, in fact it SCREAMS, "I AM A SERIES 3"
So yes I would say it is very suspicious
