Where to find my VIN number

[stuart750]

I recently put my '83 240D on the road, and onto an insurance policy. The VIN that I gave them turns out to be an exculsive M-Benz VIN that the company uses internally to determine body, chassis, etc.

Now, I've been looking to find the real VIN, and I can't seem to find it. I've looked along the dash, on both door pillars, under the hood (the small metal plate with the company VIN is there, but not the real one).

Where on earth can I find it?
