I did a search and couldn't find the answer to what I was looking for so I figured to start a new thread. Regarding Euro 360's that are already converted and titled in California: I've been told that the emissions systems is very unstable and can cause a major headache at anytime. Smog check may not always pass and if it doesn't it could cost some major $$ to get it right to pass. On another note, from what I've been told, the emission related "parts" used to convert the car for US/CA approval are prone to failure and need to be replaced rather often. Is there any validity to this? Thanks.
