You're not the only one. I'm nearly identical. Losing access to $1k for a year or two (with the ability to get it back within a few weeks) is completely a non-factor, and since it increases my chance of a $7500 rebate, seems like a pretty good investment, actually.
Also, same feeling of 'meh' based on leaks so far. I was really hoping for a scaled down S with fewer amenities, lower performance, etc. rather than something from scratch. The no dashboard instrument cluster thing bugs me, as does the fact that AWD won't be available initially (hurting the chances of the rebate if I want AWD), but I'll wait until at least the final reveal if not later to make my decision.
