Congrats on your order! I ordered my 135is (DSB, black/blue stitch leather, 6 MT) on January 10, and it went to "in transit" status February 19. I'm the opposite of you, as I got premium, but not tech, since I didn't really care about the nav and was trying to keep it under 50K. I did want to have the ambient lighting and auto-dim mirrors and needed satellite radio. Only other significant option I got was HK. I screwed up and didn't option the alarm, by the time I asked my CA about it the car was in status 112 and it was too late to change it. Apparently the VDC or dealer cannot add the alarm later due to lack of required pre-wiring.
Going from the very basic E46 I've driven for the past 9 years to this new car will be awesome, can't wait for it to get here!
Make sure and post pics in the "135is owners - show us your cars
