Streets, BTW that tracing thing won't work here in Washington. Up until two years ago we had mandatory, live inspections of every newly titled, used car (except those sold by licensed dealers), by the State Patrol. There were inspection stations all over the state, manned by who knows how many officers/techs. A hugely expensive program. Unlike some of the states back east where there were safety items, e.g. lights, wipers, e-brakes, etc. these guys mainly did a vin and paperwork check. Oh, occasionally you could get harassed big time if the officer was a male member, and didn't like hot rods, but mainly it was intended to catch stolen cars. Thank God for budget crunches, as an audit disclosed that they were nabbing something on the order of 8-10 stolens a year out of several hundred thousand inspections!!! Happily they've killed that program. Now it's a paper shuffle at a local DMV agent's office, unless the car is a "kit car" or assembled completely from parts in the absence of a title. Then there will be additional varification and the state assigns a vin of their own creation.
