When was the MBP produced/first used

Hello,

Is there any way to see when was my MBP first used? I had bought a MBP which was supposed to be new, when in fact I waited 2 weeks for the delivery of a MBP which was used in a showroom. It had tiger on, and I upgraded it to Leopard, so previous logs aren't available.

Is there any way I can see when it was produced, when it was shipped, when it was first used and other information like this?

google the sales order number ie M8359LL

What sales number? Do you mean serial number?

I bought the MBP from a certified reseller in Romania.

Its actually the model number - dont know why they call it sales number

that is the serial number. It doesn't help me at all to know that it was manufactured in July last year, when I bought it in november. I cannot prove that it has been used before, and my MBP that was supposed to be new, is in fact like a second hand one.

Plus, I don't have that number. I have only serial number.

I doubt you'll find anything that will tell you when it was first actually used outside the factory. Usually only products that have certain warranties which start when the product is first used rather than first purchased will have that kind of info. But those kind of warranties are on commercial grade products only.

There must be something...
