I got the Year One of the 1 book just a couple days ago, so I guess it was about 1.5 months since I bought it. Seems pretty cool, havent read through the whole thing yet. I also got an extra set of floormats cause the dealer shipped me two sets by mistake.
I wonder if they'll send me anything else...
Just for comparison sake, when I bought my 2004 R32, VW sent me a numbered poster. Car also came with a pen and keychain with R32 logos on them. The keychain I got from the BMW dealer was junk, used it for about a week but got tired of it knocking against the dash with every movement of the car...
The book seems pretty well put together, nice photos, high quality paper... Can't frame a book and hang it on my wall tho...
