From George B's blog post today:
Model S comes standard with a Four Year, 50,000 mile New Vehicle Warranty. An additional Four Year, 50,000 mile Extended Warranty will now be available for $2,500. Please note, this is a “Four Year” Extended Warranty, not two or three years like most Extended Warranties. You will be able to purchase this option through your MyTesla page in the near future.
Several months ago we announced a Four Year, up to 50,000 Mile Prepaid Maintenance program for $1,900, or $2,400 with unlimited Tesla Ranger visits. You will now be able to purchase an additional Four Years and 50,000 miles of Prepaid Maintenance for an additional $1,900, or $2,400 with unlimited Tesla Ranger visits. With this additional program you can now cover everything on your Model S, except tires, for eight years and up to 100,000 miles for $3,800, or $4,800 with unlimited Tesla Ranger visits.
I think this is very reasonable and am glad the service costs are not higher in years 5-8. Thoughts?
