I forgot to add this.
You can do a 100% free VIN check here and it will tell you if the VIN is reported as stolen,written off by an insurance company,or has a loan against it.

SC doesn't require registration on street legal bikes under 50cc.This is good and bad.Some people have bought scooters that will run faster than 25mph and still have a engine size under 50cc.Technically,if a bike is capable of breaking 25mph,it is supposed to be registered,titled,tagged,and insured.Most of the time,you won't be bothered by the local cops but troopers will single you out.So, if you have a small road legal bike,you can skirt the law by keeping it under 25mph.I wouldn't do it but I know those that have.
