They might not hassle you for being late but they might question the collector or limited use registration. If that is still current you might be ok. Aren't you supposed to go to dmv every year so they can record the odometer reading to verify you aren't putting more than 3000 miles a year on it? If you never went and had that updated they might hassle you and I'm guessing they will. Keep your fingers crossed and take a bunch of paperwork and it may overwhelm them.
