Lease FTL.
Buy FTW!!!
Seriously, right now, dumping your money into a lease right now is as good an idea of burning your money in a fireplace. $780/mo is RIDICULOUS. That's exactly what your payment would be for a 5 year loan (4 years with $5K down). And at the end of the loan, you get to KEEP the car!

Invest into equity if you're going to throw money like that out the door! Worst case scenario is that if you can't afford the car, you sell it back and even if you lose a few hundred dollars, you didn't loose $28K like you would at the end of this lease! (780x36= $28,080! CRAZY!)
Another problem is that the lease will hold you to a maximum mileage and any thing they need to fix/replace when the car comes back, YOU'RE LIABLE FOR!
When you do the math, you should realize that the lease = lose/lose. (It's never your car and you're just paying really high rental rates!)
Sorry, but unless the you're writing off the entire lease on your taxes (which you probably can't) it's not worth it to ever lease.
