my family always paid off for my new car/2years

my family always paid off for my new car every 2years.
during 6 years, i have driven 5 brand new cars.
first 3 were same brand with 3 different color.
i guess, if you can afford to pay off, better do it.
otherwise, you still can't keep extra money in your account.you can spend rest of money by buying fine clothes, traveling,dining in the fine restaurant.
