. To try to make the case (as a previous poster did) that they are more economical because of residual value is silly.
Sorry, you're cracked.
The actual cost of ANYTHING is what you paid for it, minus what you sell it for later. If you never sell it, either by choice or because there's no market for it, then it's just what you paid.
A Lexus is often more-economical to own than a Chevy for just this reason. It costs more up front, but it retains value infinitely better. If you pay $50K for a Lexus, but sell it five years later for $35K, it was cheaper to own than a Chevy that you bought for $30K but got $7K for after five years of ownership.
If you're not thinking that way, then you suck at math.
