I too went through similar thing with my TR3. The actual VIN on car and on ownership were quite different, although I had a complete paper trail and Heritage Certificate as documentation. In my case (I'm in Ontario, Canada), I talked to a friend who is a cop to get his input. His quite correct advise was tell the truth, but like you I was very leery of the hoops I might have to go through. What I ended up doing was getting a letter from a certified used vehicle dealer, certifying that he had inspected the vehicle and that the VIN matched the one on Heritage Certificate. With that I went to motor vehicle guys and presented my case. Took a call to head office, and some head scratching, but they issued new correct ownership papers. The key was to have as much documentation as possible. In my case, the Heritage Certificate was the clincher. One thing that was not changed was the colour, but the agent I was speaking to told me not to push my luck that day and just come back to change the colour when I got the car on the road. Took her advice, said thanks, and left with a smile and considerable relief that the whole process went much better than I had imagined. Hope all works out for you. Cheers, Mike
