It's interesting that Netherlands seems to assume all electric cars are green. But Singapore actually calculates the carbon emissions per km and finds the Tesla Model S to be very environmentally unfriendly: the Model S attracts a surcharge of $15,000 while the BMW i3 gets a rebate of $30,000 [1].

It seems the rent/loan/buying tradeoff would be independent of the choice of car.
Say a price of a brand new Tesla is 100k Euro. If you got a loan from a bank to buy it, you might be paying back 1000-2000 euro a month just to pay it back in a few years. That is quite a lot. There are companies however, which let you part-lease or part-hire or however they call it, when you pay roughly 1/2 of the value of the car over 3-4-5 years, but you don't get to keep it at the end. So you might have a brand new Tesla S, for say 400 euro a month - which is very affordable. The only caveat is that you don't get to own the car at the end - but for a lot of people that's not a huge issue.
If you buy both without a carrier, you might pay 400 EUR for the mid class phone and 800 EUR for the premium phone. The price difference no looks huge.
(The difference in acucmulated prices is the "buying" price of the phone)
The weights of the Tesla Model S and the Mercedea Class S are pretty much identical.
These two statements are not mutually exclusive.
In The Netherlands cars are taxed on multiple factors[1] including CO^2 emission, type, and very significantly on weight.
In Tesla's case the weight is being heavily offset by the lack of CO^2 emissions, whereas the Mercedes gets all the taxes of a normal gasoline car and the weight tax on top of that.

Living in the Netherlands, the price of a Tesla is around 100.000 euros. However, if I can lease the thing, the actual cost (due to tax benefit, etc) drops like a rock to a level that compares to a small, cheap car. For full electric cars you hardly pay taxes because the government wants to stimulate this clean way of transportation.
Now comparing to a Mercedes with a similar price is wrong, simply because the Mercedes with a similar price is costing much, much more in day to day operation: more tax (heavy car = high tax), no green car, so more taxes).
I believe that at least for the Netherlands, most hybrid or full-electric cars are driven by people that have a company car. We just love tax refunds. We hate the hassle of charging, so many hybrid cars in 2015 (Mitsubishi Outlander is a good example) were driven on petrol - not electricity.
