Huffy Savannah Cruise bike I have a beautiful old Huffy Savannah bike and would like to know how old it is. The serial number starts with a 4 but that doesnt help me. Is it 1984, 1994, 2004, etc??  I cannot seem to find anything online about this bike other than some other ones for sale.
Its a moderately modern version of a fairly traditional design.
The rear derailleur suggests its in the last 20 years, and the one-piece crank implies its a lower-cost variation.
The alloy wheel rims also show is relatively recent - a 1984 era bike would have had steel rims.
The zip ties holding cables to down and top tubes are a bit anachronistic, and the left/front brake cable is flapping in the breeze - I'd loosely secure that to the other cables in front of the headset. 
Not sure if the handlebar has reflections or rust in the photo, could be either.
Looks like a loverly bike to me - as long as the moving bits move smoothly, and the brakes work reliably, then it should be an enjoyable ride for decades to come.
