A ref ticket is the reason I sold my 240sx. I DID get away without popping the hood, claiming "it requires tools to open" due to the RHD conversion. HOWEVER, he looked under the car, saw no cat, and wrote the ref ticket anyways.
I traded the car away before the court date (mine would have been a $780 fine without correction, by the way), so I was able to pay a $35 processing fee and they dropped the charge.
HERE'S WHERE I GET MAD: If the state gave a flying f@ck about emissions and saving the planet, why did they let me off by just getting rid of the car?! The release of liability clearly stated that I sold it to another California native, so they can obviously assume that it's still polluting our streets, right? So, they much JUST CARE ABOUT THE MONEY!!! Total BS- almost every aspect of our government here in California is broken.
BTW- the ref station in Sacramento is OPEN, last I heard, so you're not getting out of the woods that easily.
Someone mentioned smog control in a pre-1950 vehicle. If the officer recognizes the engine as a smog control era lump, they need to conform to those laws- you smog to the engine, not the chassis. No, this doesn't mean you can put a pre-smog engine in your '95 Altima, either- no going back in years. Also, the new engine has to be from a similar classification of vehicle- no Power Stroke diesel in your '78 B210, I'm afraid...
The whole system is designed around making money. If they cared about the environment as they claim, the smog test would only go off of what comes out the tailpipe- everything else is bureaucracy.
If you need somebody to transfer your title to so you can show them you sold the car, let me know- I'll "buy" your car and "sell" it back to you after court!
