Most (if not all states) recognize out of state plates as legal registration of a motor vehicle. Most states will also readily issue a title for a "grey market" vehicle, if they have a legal title from another state - U.S. vin or not. I've owned a grey market eurospec Mercedes 240D as well. It had no U.S. vin. As for ABC's claim that they will not pass emissions. This is false. The first minitruck to be registered for road use in Texas, was registered in Tarrant County - an emissions county. The truck passed, after the owner had a leaky exhaust pipe fixed. If one fails an emissions test, then there is likely some kind of problem with the truck that requires attention. Mine was the second one to be registered for on road use. We have no restrictions whatsoever as to what roads we may drive on. I've had mine on state and U.S. highways, as well as local interstates. I know that ABC does not like the idea of these trucks getting used on road. However, the EPA cannot deny state soverengty. If a state decides to allow these trucks on the roads, there is little that the EPA can do about it, beyond threatening the states with the loss of highway repair funds.
