200sx is reliable but if you really want something reliable just get a 95-99 sentra. only thing is if you get the 200sx make sure its an se-r or you will really wanna do an engine swap. the se-r platform just rides better than the ga16de although the ga is really reliable its just soooo slow.
then again i have a 96 accord and i really like the reliability of that too ( 130xxx) and it still runs strong. my parents bought it from the lot brand new and it has never had any mechanical problems and has always ran great.
