Start buttons really aren't a luxury feature...unless a RAV4 is now considered a luxury vehicle?

Two sliding sunroofs would not be possible...not enough room for the glass of the first roof to slide before the second roof. You could get two flip-up roofs, but that would just be ghetto. The other option is the Webasto panoramic roof. The entire front half slides back over the second half. However, it is an aftermarket addition (with a great warranty, though) and the air diffuser makes noise at 80+ mph and especially on windy days.
