She lists Massachusetts as one of the states, but I don't see it.
MA has a rolling 15 year exemption on emissions. Anything older than 15 years just doesn't get it...even the plug in OBD2 cars. As for costs to register and such, the older the vehicle, the cheaper it is generally. My '88 and '00 are MUCH cheaper to register and pay annual excise taxes on than my new stuff. I have a vanity plate on my '88, so it's a little more expensive, but all in with regards to gov't fees (registration, excise, inspection) i'm in for $135/annually on that car. My '23 Explorer ran me just under $1K in the same gov't mandated cost...mostly excise.
I don't see anything in the pipeline from MA either. I'm in a few local groups where this stuff gets spotted pretty quick when someone tries to pass a new restriction. So far they haven't paid much attention to the handful of older cars that drive on the roads 3 months a year here.
You know what forces people out of older cars in MA? Rust from all the damn salt in the road. Seeing something older than 15 years driving around as an every day car around here is rare because most vehicles start rusting out around 150K miles
CA is just a whole different level of suck with regards to vehicles. Ironically I am about to hop on a plane to CA
