I saw that you don't know the e30/Z because she isn't written in the title "Z series " . I come to speak to you about Z1...
Do you have Z1?? In Europe and in Japan it's a "rare" and expensive car. There were 8000 specimens/cars in the world. A particular model with the doors which goes down. The engine was the M20B25 of the 325i E30 ( 171ch ).
