The front end cost can be reduced by state and federal tax credits if you buy in the next 6 months, depending on the state. Tesla USA sales are around 140,000 cars thru Dec. 2017, but when they get to 200,000 the federal tax credits get reduced. You will also save about $10,000 in the first 5 years based on current gas prices. BTW, all currently new 2017 Tesla Model X vehicles and presumably the 2018 models come with fold-down back seats to add to the storage capacity of the vehicle, and the 4,000 lb. towbar/hitch is standard.
In the past 12 years I have owned 18 different vehicles. I purchased the model X 100D 2 months ago. It accelerates faster than my Golf R, Nismo 350 Z, or Infinity M class. The car is as luxurious as my MB E63 AMG and rides as well as my Cadillac CTS-V. Recently I had to take it off-road. I live in the mountains and had to pick up a sick child. The roads were unplowed and recommended chains only. I simply raised the suspension and easily drove miles and miles in 2 feet of snow. It handles as well off road as my Toyota Tacoma. Then driving down the canyon I didn?t have to hit my brakes once because of how the vehicle torque charging works. The canyon is a 65 mph 5-6% grade for 20 miles. Finally, because of the torque charging my battery charged on the way down the canyon. I can?t express how impressive this vehicle is. Elan Musk not only built a competitor he built a game changer.
