The seller explained us how a lease was so much better financially than outright buying. He was completely wrong on the fundamentals: basically with a lease the car company makes you a huge favour because after the three years are up the car is worthless but they’ll take it back and lease you a new one anyway and you get a brand new car. Whereas if you own your car is worth 0 at year 3 (???) and you have to pay 100% of the price of a new car again to get a new one.
Never mind residual value or that you are allowed to keep a car longer than 3 years.
Must be working because most of my relatives friends have a leased car.
