I think that's a 2007 bass. "D" for deluxe, and "Z7" for 2007. "Z" is the 2000s; "N" is 1990s, for example.
I had maybe 4 or 5 of those Deluxe. The early ones had awful fret work, really awful. But they were available in rare colors for lefties, such as transparent red and natural. All generations of this bass sound great, both the 9V or the 18V. I found the preamp/pickups a little prone to picking up interference, and even with the EQ set flat, there was a bit of hiss coming through. Never totally dug the active sound -- I prefer passive in general, but great-sounding basses nevertheless.
What made me get rid of them ultimately was the shape. I don't like basses with small bodies much, especially on 4-stringers, and I didn't like the 22 frets either, because the design made the 1st position feel farther away than a regular 20-fret Fender. The full-size Fender Jazz body shape is the most comfortable to me.
These could be had for under $1000 all day long. At the end of their life, Fender wanted $1500 for them. I also had a 2007 one, and it was really sweet, super light, and the fret work was great. Fender definitely made an improvement in quality control and fret work around 2006 or so.
Congrats on the score and enjoy. Fender rules!
Here are some of my former ones:
