5 weeks on mine.

 

6 weeks for me (is350 w/ML)

 

I special ordered my 2008 IS350 in early June. I was told to expect delivery in mid to late September.

 

Good news! Dealer called me and offered me the same car I wanted but it had the luxury package which I didn't really want to pay extra for. I negotiated to $250 under invoice before accepting the offer. I waited almost 8 weeks before he found one that was going to be inventory allocated to their store.

I still have to wait 3-4 more weeks but at least I will get a VIN number tommorow.
