Also you mentioned a 1995 landcruiser as a comparison, so if we use the costs of replacing oil every 6 months, along with fuel costs etc. You will actually end up saving money even if you kept the electric car for 20 years and then replaced the battery.

Driving an electric vehicle will save you between $1320 and $3070 every year on average compared to petrol, diesel and hybrid-powered cars, the data revealed. An electric vehicle recharged exclusively on solar power will save between $820 and $2570 in fuelling costs.

1320 x 20 = $26400

Cost of oil

So lets say you bough some cheap oil every 6 months and only needed 5 litres and costs around $30 and an oil filter of $15 after 20 years it would cost $1800 aswell. Notice im using very generous pricing here and in reality it could cost alot more.
oil = 30 x 2 x 20 = $1200
oil filter = $15 x 2 x 20 = $600


Now lets compare the cost of replacing a battery.

Bottom line:the cheapest estimate for an out-of-pocket, uncomplicated battery replacement on the Model S should cost about $12,000-$13,000 for the battery, $100-200 for miscellaneous parts, and $500-600 for labor. This puts the grand total at around $13,000-$14,000 for a full Model S battery replacement.


Essentially just on the costs of fuel and oil, compared to an ev your paying double.
