They are still cars, but I expect the depreciation will be at a slower rate, rather than “typical depreciation methods”.
My Ford Ranger went several hundred thousand kilometers, but was on its third engine when it went to the junk yard. My 2004 Prius had several hundred thousand kilometres when it was totaled. But over those 10 years it had not been improved. The 10 year depreciation resulted in it having very little value, even though it probably would have gone several hundred thousand more kilometres.
My 2009 B4000 has very little resale value despite having less than 90,000 km. It has not deteriorated much but it has been “left behind” because it has not improved over the years.
My one month old Tesla has already had minor software improvement.
Yes, it will depreciate over time, but I expect the depreciation to be based on a new paradigm of depreciation rather than the “typical depreciation method”.
