You don't actually put up $50,000 or whatever the price is,you pay for the bonding company to stand behind you.To have my repair plate I needed a $50,000 bond.It was $156.the first year,then about $100,then dropped to about $60.per year after that. N.H.does not do out-of-state registrations,you need a residence here to do it.We are non-title after 15 years,and law enforcement is pretty careful about impounding car for little reason.Suspicion is not a good reason to take your car,as it has to be returned to you in the same condition it was in if it is not stolen.They don't want to haul it,store it,and haul it back because of some little detail.Then again,there is no tax involved here,the only fee to register an antique is $6. to the town and $6. to the state.There is no incentive to nitpick on antiques here.It pays the state the same for a Duesenberg as it does for an A.If there is suspicion of something off,(other than out and out stolen) they will pull your plates until settled.
