In February, 2005, Jeff presented Jay a gift "From one Car Guy to Another"
in appreciation for Jay Leno's generous hospitality in his ultimate garage of classic cars.  The gift was the 1914 "Cactus Derby Master Driver of the World" medal in bronze, shown below.

Here is Jeff on the Tonight Show set after the show taping, with Jay and Steve Proctor, prior to heading to Jay's Big Dog Garage.
