Opinion on this '78 GMC?

[Tyler]

Hey guys:

I was prospecting through the local sell it yourself lot here in town and I ran across a 1978 GMC lwb truck with some stuff on it I've never seen before.

I didn't have my camera with me to get pics, but I'll describe what it has via the RPO sticker that was laid on the dash:

High Sierra
350 4bbl
chrome bumpers f &r ,brite grille, wheel trim
sliding rear window
deluxe hubcaps

Ok that stuff is pretty ordinary, but look at this:

U16 gauge cluster with tach
ZQ2 convienance pkg
K43 poly-wrap air cleaner

Also has cruise and interval wipers.

Here is the most unusual part of the truck:

It has AV5 high-back bucket seats, and has a console included. I thought it was an add-on but it's right there on the option sticker.

The truck itself definitely looks it's age, but I think some of these options make it more uncommon. It's advertised for $700..what do you guys think?
