"Minnesota does not have a mileage restriction for collector class vehicles. Collector vehicles are to be operated only as a “Collector’s Item” and may not be used for general transportation. Generally driving to and from collector events (shows, parades) is acceptable. Check with local Law Enforcement for more specific issues."
I really doubt youd be pulled over for those plates.. But its possible. Not like they know where you are going, you could just say you are going on a test drive since you just got X mods done, who knows. I wouldnt worry.
