I've got a facelift 2000 2L auto and it's fitted with the earlier GM 4L30e transmission. It was the 2001 - on models that were fitted with the steptronic autos. I may be stating the obvious but why buy an auto if you really want a manual? Although I'm perfectly happy with my earlier box I've had a few Beamers with the later auto box and I wish I'd gone for one of the last Z3s with this box. So there you have it. If you want a manual wait a couple of months for the market to get going and then you'll have a better choice, for an auto wait for a 2001 model. An X reg will be just before the March 2001 road tax changes to ones based upon manufacturer's emissions statistics which are slightly dearer to tax. Be careful though, my car is a 2000 X reg with the old auto box. It's the 2001up to March that are still on the old 2 tier road tax.
