I haven't properly checked off all your figures but seem ok. The biggest unknown is if it will really be worth 48% of initial cost in 5 years. I can see the arguments for a high long term value, but suspect it will drop more much than that - e.g. the cost of new Tesla's will surely drop a lot in 5 years, or they release a new cheaper model, which will make second hand prices of Model 3's drop. I'm assuming more like about 30% of initial cost price after 5 years to be safe.
Remember you might save $6000 in fuel, but you would have tax deducted 70% of that to save maybe $1500 more on tax than you will with a Tesla.
If you have a high tax rate and can tax deduct most of it then buying a new car every 5 years does not cost you that much, but with the saving that come with a Tesla it is even better.
For anyone doing 15,000km+ a year the figures work out quite well, may not end up being as well as you've listed, we'll see. But if not going crazy on the performance model (like me
then the figures work out well compared to even keeping a older ICE.
One thing too I haven't seen a lot of discussion on here is charging off peak to make it even cheaper to run. Different in different states but here in SA it is about half the price for off peak which was only 11pm-7am, but now also 10am-3pm due to the amount of solar we have here. So I can charge at half rates for 13 hours of the day, and even on 3 phase so at full 11kw speed.
Due to stupid previous SA gov incentives I'll be charging during the middle of the day at 18c/kw, which does not take off my solar exports and exporting the same solar as I always have, at over 58c/kw. So i'm getting paid to charge my car if I do it during the day
