Been thinking bout that car since this morning, it might have been a diesel engine in it, it was noisy and emmitted blue smoke is all I remember. Never had a drive in it but he did have another Citroen , somewhat newer, maybe 60`s era that was just a noisy lil bastage, white in color and rode about like a hay wagon.Speaking of Citroen`s there was one stored in a garage not far from where I grew up. It belonged to a Senator that had a summer residence here on the coast. I had the job of recovering all the exterior surfaces of that garage one summer when I was about 17 -18 years old. All cedar shingles to keep it looking vintage and left to silver out with weathering. Anyway the Citroen was a 36 and looked much like Robins pic and just like the pic I posted below. I think it had some sort of a two stroke engine in it as it smoked a blue stream every time it was started, would have made a great rod but the owner wouldn`t even entertain the thought of selling it.
