Maybe I'm getting shafted, but I've been paying on my 77 that's been in storage and unregistered since 2010. Also, those taxes have been assessed, you don't pay within their window, additional penalties, fees and interest start accruing...so the next time you do have to register it, you'll get hit with it. Happened on my Bronco last time I let it sit for 6 months, registration lapsed for 5 months...and on vehicle they valued at $700, it was an additional $25 in fees. Now had I sold that Bronco, does that assessment just disappear??? I dunno, or does your name just float out there with an uncollectable tax liability attached to it???
