Wisconsin you can get either Collector or Hobbyist plates if your car is 20 yrs and older

. For Collector plates it must be
100% stock
Cannot be driven in January (as to not complete a full year of driving, plus who would want to during rust season?)
Must have a regular registered car as well
One time registration fee
Hobbyist plates
Can be modified
submit photos of engine bay, interior/exterior
Can be driven year round
Rest of the rules are same as Collector Plates
Ontop of those options, WI also doesn't do emissions anymore for OBD1/1995 and older vehicles

.
Unlike where I live now (though my Coupe is still registered in WI with current tabs) in WA, for Collector plates it needs to be 30 yrs old and can only be driven on special occasions

. Emissions are required on 25yr old cars and newer in the Greater Seattle-Tacoma area, but pretty much the rest of state doesn't do emissions lol, only around the major city area and outskirts haha. No inspections like TX, PA, NY, VA, etc do, thankfully.
