When you find yourself telling people that things are a lot more expensive "than when I was a kid", you know you're starting to get old. "How Much is That?" is a great tool that allows you to calculate relative values of money between the years 1907-2005 with a simple click of a button. Maybe that old Cadillac you bought when you were 20 years old wasn't so cheap after all.
