I would buy the used economy car. I'm not sure how many miles you're thinking, but let's say an Altima with 30k miles on it costs $15,000. Let's say you put 10,000 miles on it.

Option A. Buy the used Altima above, and after 5 years you've paid $15,000 and own an Altima with 80k miles on it

Option B. Lease for 5 years. You paid $2,000 + $240*60 = $16,400. You paid more and you don't own a car.

You can fudge the math a bit, but Option A is almost always going to work out better in the long run.
