Hi kodachrome,
When I bought my 1994 850CSi last year, my insurance company needed a valuation before they would provide Classic/Vintage insurance cover.
They had no listing whatsoever for the BMW 850CSi, which as we know is a much more rare and valuable beast than the regular 850i.
So I had a friendly RMVD sign a written valuation for my car on their letterhead, including an appendix with pictures of the car.
The car's value was derived from its rarity, condition/history and recent sales prices overseas.
This valuation was acceptable to my insurance company, and should therefore satisfy your import company's requirement for a "Registered Valuation".
Look forward to seeing the car when you get her complied and registered for the road.
It is the 7th RHD 850CSi to be brought to this country, and will be one of just five road-registered examples here.
Let me know if you still want to be included in the NZ E31 Register.
All the best.
