Don't do this- I speak from experience as my parents did the exact same thing (leased a brand new Honda Civic) when I turned 16. I wanted an old Mercedes, which I thought was cool AF and could afford with the $4k I had saved from some very generous "grandma birthday money" and a job working in the kitchen at a ski resort, but the thought of me driving a car older than myself with no airbags and that had to be plugged in during the winter to keep the engine warm (diesel, in the snowbelt) drove my mom to a breaking point where she insisted on leasing a new civic, having me contribute my aforementioned savings, and having my parents pay the balance. All in, it was about $9-10k, if I recall correctly. And woo, I got a new car so yeah, I was on board with this plan.
Teenagers tend to have really, really bad perception and parking skills, as they've never driven before. Definitely scraped those bumpers, not to mention ate lots of fast food in the car, spilled plenty of sugary drinks, and lets just say "lit up a bunch of greenery". I went to college with a year left on the lease, and it was driven by my little sister who had the same penchant for Phish, frappucinos and midnight taco bell. And when the lease ran out, they were still "down a car" so considering the condition it was in and how much they'd get dinged by the dealer for that, wound up buying out the lease. All in all, it was a $18k car.
...for the $10k cost of the lease, just buy something like this instead, and let them take it with them to college...
