The P-51's first flight was in October 1940; in service January 1942.  Top speed 437 MPH. The unit cost around $51K (1945 dollars)
The F-22's first flight was September 1997; in service December 2005. Top speed ~1,500 MPH, The unit cost ~$150 million (2009 dollars)
 
Here they are flying in formation (the F-22 pilot must be idling and has flaps extend to be slow enough).
