Buy used car. Less than 2 year used with less than 15K miles will save you lots of $$$$ (vs brand new price). Nowadays quality of every cars are good and still under warranty even if you buy used. Do lots of research.

Leasing car is convenient if you like to change every 2 years.

Buying brand new is if you like the new design/function of car and can't wait to get it. Or if you have loads of money and don't care much about saving.

Choice is yours...
