M30s aren't bad cars when kept up and taken care of, and yes, they are loosely based on the 240SX and do share a lot of things like suspension parts with them. The only bad thing is that it is convertible because they always end up leaking. Technically the M30 was never built as a convertible. The ones that are convertible Nissan did after they arrived at the US port from Japan. It was kind of an "afterthought," for lack of a better word.Originally Posted by sped56737
