We were going to do this for the 58 bus but sold it instead. You will need a bill of sale from the owner you purchased the car from, this does not need to be the last registered owner- in our case, who knows who that was. Then you send the bill of sale, the vin number and i think it's 13.00 to ICBC. They will then send the last registered owner a letter to make sure that they have sold hte car and everything is legit. If the owner confirms this, or they do not respond within 6 weeks (i believe) they will issue you new registration papers.
They were really nice to me when I phoned and explained it was a vw. I was very suprised at ICBC that day.
