Just enter the last 7 digits of your VIN number, mine for example starts with T and is followed by 6 numbers. It can only be done once your car is built.

This VIN check is fun... you can see the specifications that other people have chosen and, of course, check your own!

My car was built on June 12th and I should have it next week.
Looking at the VIN numbers either side of mine, they obviously build batches of cars in the same colour... but this was not obvious when I took the factory tour a couple of weeks ago.
I wonder if the widely varying delay times that people are experiencing is due, in part, to the way they are building cars in colour batches?
My Cooper D was due to be delivered in early May (before the engine issues)... not long to wait now.
