That site says the title is active but the registration expired 6/30/2000. Probably means it moved out of the state when it was up for sale back in 2000, or its still in FL sitting on blocks somewhere.
It is currently still registered in Florida. If you look at the column on the left it says, Title Status: "Active" which means current. My wife is a loan officer in the state of Florida and this is a public site they use that lets them check to see if it is current and with or without a lien.
Also, it is possible to find out who the current or past owners are. I just did one a couple of months ago.
