I thought Progressive still did customs.You might try Unitrin Specialty Insurance,I was with a sub company of theirs called US Insurance for my WG but they dicked me around pretty bad after a semi ran me off the road and didn't stop.The biggest problem was they said my bike was worth 7K and the cheapest replacement started at 12K.You might want to look them up and see if they have policies that will cover the bike for a stated value.I don't have their # anymore but you should be able to find them on the internet with no problem.Good luck,customs are getting real hard to insure now.
Oh,if you ever need to get a realistic price on a bike,go by Kelly Bluebook.NADA usually comes in closer to wholesale or trade in for top price.They really suck on scooters.
