My wife just bought a 2007 Volvo for right at $19,000 which new (2011 model year) costs $31,000. How's that for depreciation? We saved $12,000 by buying a four-year old car. Buy that $40,000 car four years from now, and get it for $26,500 (30% depreciation). Self-control is a better thing to have than a $40,000 car, trust me.
