Here is an
example. But a roadster is not a fair comparison for the following reasons,
1. Roadster was a limited run, 2500 and fewer everyday (they are crashing)
2. Roadster had far more issues than Model S. And the owners had a greater appetite to deal with the issues, and Tesla's willingness to help was greater .. at least used to be. Today it's sorta sad that Tesla is happy to charge them $30K for a battery upgrade, but they won't throw the roadster owners a bone by enabling supercharger access
3. Roadster owners are not putting as many miles on the car as Model S owners. So many roadsters have very little miles on them.
4. If you think Model S repairs are bad, look at the roadster.
Secondly comparing it with an ICE is also not a fair comparison. Yes it is less complex than an ICE, but a 10 year old ICE can be fixed by Joe the mechanic. Your Model S cannot. And Tesla goes out of the way to prevent a third party from fixing it.
And while EV has less moving parts, your Model S has a LOT of other parts in the car that could fail, and are not fixable without Tesla's super-expensive and often unwilling help. 8 years from now, what incentive does Tesla have to help you? They do have a LOT of incentive to sell you a new car though.
Things that could go bad with your Model S .. 8 years+,
Door handles
Touch screen
The non touch screen
steering wheel buttons
heated seats/airbag sensors
Latches, Hinges
Pano roof (motors there?)
Other wiring
Bulbs going out
Your usual car accidents.
etc.
Most of those, your neighborhood mechanic won't be able to fix. Tesla won't sell him/her the parts, or make the manuals available. And Model S while > roadster, is still a small segment of the market, so the neighborhood mechanic doesn't care as much for your business either.
Long story short, a 2013 Model S can be had for as low as $40K today. That's 50% value loss in 3 years. In 8 years, your Model S will be .. $12-$15K.
But if you think that's bad, look at a Mercedes S class or Jaguar. .. plus you spent $0 on gas.
