It has the '68 fender lamps, a nice touch IMO. Many options that I can see, Comfortron, Twilight Sentinel, Guide (headlight dimming), probably power seat, vacuum power door locks, power windows, rear defogger, but oddly, missing cruise control.
I've always liked this body style of Eldorado. It's design was ahead of it's time, but it was sill clean and handsome. The later examples added bulk and (in my opinion) excessive amounts of unnecessary kitschy design flourishes that muddled the overall appearance. From an aesthetics perspective I think this one is just about perfect.
I also think that the 1st series Eldorado's are the best looking ones ever made. This one has some nice upgades and the factory AC is a big bonus over the Gold one on BAT last week, but the Gold one was a no vinyl top car. Much better looking IMO. But that is not meant as any slam on this example. Very very nice car.
