We have a Tesla and most owners love them because they're good cars. Cost of ownership is next to nothing and our Model Y had next to no issues so far (scratch on seat when we picked it up which they replaced with a service appointed).
It costs less than $2 per 100 km to run while the prior car cost closer to $20 per $100 km in premium fuel. Also no oil changes or other significant maintenance (spark plugs, transmission oil, etc.) We save $3000 of gas per year and we're in a luxurious/premium car. What I don't understand is why anyone would buy a GLC/Q5/X3 over a Model Y. Who wants to spend $15k on gas in 5 years?
