I would get the dealer to walk through exactly what the options do, as there seems to be some different understandings around. Then again, your dealer may not be an expert either.

IMO, seat memory, and curb function on mirror are both very useful.

Also, I would have the car lock automatically. Only downside is access in an accident, and I recall that the impact sensor unlocks all the doors in that case anyway.

Relock after 2 minutes: you have a good justification for it, downside is it may be possible to be locked out (not sure on this).

My steering wheel automatically moves out of the way.
