Well, I'm taking advantage of the fact that the $40k is refundable. In talking w/ my wife and showing her the design studio, it looks like we're headed towards a heavily optioned car. Wife: Oooh, I like the Shasta Pearl White. Oooh, I like the panoramic roof. Me: Oooh, I want the 300 mile pack. Both: Oooh, sport would be nice depending on how much it costs. So I'm rolling the dice that a Sig will be cheaper than a similarly optioned standard car. If it isn't (I assume we'll have the full option list before we have to commit to Sig delivery) then I'll drop back to a standard 300-miler. I figure the money isn't earning me much in a savings account so why not?
Keep in mind though, that you DO lose your spot if you downgrade (according to the rep that I've been emailing with anywho)
