Citroen BX GTI. Bristol UK
A rare survivor. Apparently lots of these were scrapped and their engines removed to go into Peugeot 206s as they had better handling.
Nearly got it in frame!
If it had not been misfiring I would not have the camera out and turned on in time.
I remember drooling over the outlandish BB Porsche's in Road & Track when I was a kid!
