Okay, so you've already gotten the advice that financially it doesn't make a whole lot of sense. The most financially savvy thing you can do is buy the worst used car you can tolerate with low maintenance fees and drive it until it dies. There are a few things I think worth noting about leases if you are thinking about it still.
Of note, I've leased 4 different cars, all from Honda, throughout the years so my perspective is entirely through their leasing program.
1. You have the option to purchase the vehicle at the end of the lease for a predetermined price. You should compare the total cost of the lease + end-of-lease purchase price to the cost of buying the same car new. In my Honda leases, the cost difference has been less than $1000.
2. When you end the lease, there are several options. You can turn it in(sometimes with a high disposition fee which you should look at before leasing), you can buy it and keep it(probably the worst option), or you can buy it and sell it for a profit, including as a trade-in for your next lease or purchase. My most recent leased car was worth $1500 more than the buy-off value so I was able to trade it in and lower my lease cost.
3. Most leases will not charge you for "normal wear and tear" and additional damages up to a pre-determined amount($1500 for Honda). I've dinged up all my leases and never been charged.
4. The car you want now might not be the car you want in 3 years. Being in the military, I can be moved anywhere on a 3 year cycle to drastically different climates and areas, so the short term commitment works well for me.
5. What you negotiate is down payment vs monthly payment and the annual mileage. The cost of the lease is advertised upfront so there's no haggling or worrying about getting ripped off.
6. Most vehicles will have very little in maintenance costs in the first 3 years. I get oil changes less often then I probably should and change the wiper blades maybe once the entire lease duration. It's not my car, so paying for additional maintenance isn't in my interest so long as the car is drivable at the end of the lease. In convenience alone, it's really nice.
7. New cars have nice features that old cars don't. Having Android Auto was a huge plus for me, as are the additional safety features such as lane departure and early braking assistance.
8. New cars also have better gas efficiency. My current car gets 50mpg, which helps offset the cost.
9. You don't have to sell it when you're done with it. I personally don't have the time or energy to take pictures, meet with potential buyers, do all the paperwork, etc.
Again, leasing is a loss financially but there are some nice advantages to it. You can decide if its worth it or not.
