What a collection:
Still curious to know more about this Sierra and it's VIN, anyone?
Update 18-5-2020: Well, that was easy. I send an email to the museum and got a response today.
It's VIN 9173 ... and guess what, that was the only one missing in my register, meaning no actual photo and it's current status. How cool is that!
