Hi All, I am trying to figure out if I should get 40k or 60k version.. but if I get 60k version, I need to remove some options... and one of package is the Tech Package ($3750).. is it worth it?? From the list, here are my opinion / question: Tech Package Takes the most technologically advanced vehicle ever produced to the next level. Use of innovative lighting increases efficiency. The Touchscreen becomes more informative with turn-by-turn navigation and unprecedented rear cargo space opens with the touch of a button. Delight in the following features: Xenon headlamps = nice to have but not a must Electrochromatic side mirrors = what is it?? LED foglights = nice to have but not a must Convenience lighting = what is it?? Is it like ambient light in some cars? Without this, is there anything else? Power rear liftgate = nice to have but not a must High definition back-up camera = nice to have but not a must Homelink = nice to have but not a must Turn-by-turn navigation with seven years of free map updates = nice to have but not a must Automatic keyless entry = what is it? Without this, do I have to press on my keyfob to open door or come to the car and press a button on door handle like other luxury car? From all the items in the tech package, i might really want only the "automatic keyless entry" which means the package is not worth it... please let me know your opinion..
