I need to commit to my Model S specs in the next 2 weeks. I was planning to order the 40 KWh but would love to hear from someone who has one. OR others that have been though the decision process. My primary use is a 40 RT commute. Weekends maybe 120 mile RT event. Longer trips I can use my wife's gas car. Live in South Florida .. so no worries about cold , but interested to know how much a drain AC is. On paper I should not need to spend the extra $10 K for the 60KWh . But i would love to hear from others. Thanks!
