Because then you have an asset. A depreciating asset, but an asset. It's like renting an apartment because you don't want to buy a home.

You're going to incure maintenance costs whether you lease or buy. Leasing is for two situations:

1) company vehicles that are able to be written off for taxes
2) people who want a nicer car they can afford, i.e. morons

I don't see an arguement.
