I think one of the things that amazes me day to day is how much is included with the Model S -- so many things that I paid for in other vehicles is standard. The last new car I bought was a 2001 Toyota Celica. After buying it, I paid around $2500 for a aftermarket GPS/Infotainment/iPod system, and $700 for LoJack to be installed. If I had added Bluetooth integration it would have cost another $200. That's almost $4000 in features that comes standard with the Model S.
Recently, as I passed the 12,500 mile mark I took my Model S in for the annual inspection. They found that my passenger door handle was malfunctioning and replaced it at no cost. For $600 they replaced my windshield wipers, checked everything, rotated the tires, replaced the batteries on the fobs, and gave me a loaner for the day.
I drive less now than I did in 2001, and after a year in the Celica, I had accumulated over 20,000 miles. On my Celica, I had to do the following: 6 oil changes, 10k, 15k, and 20k services. Total cost of oil changes and services for the Celica in 2001: $750. That cost does not include loaner rentals when it went in for major services, which could easily add on another $200 or so. On my Celica, I also had to replace tires at 30k (3 years later) for $450. I expect I'll have to do the same for the Model S (if not later -- the amount of tread left after a year is pretty good).
