You're a private seller, so retail is irrelevant (+ keep in mind the retail value is for a MINT condition example), not to mention NADA is usually on the high side. I've found KBB to be closer to reality (though even that can be high sometimes depending on the car). Personally, I would not pay more than around $1500ish if it's in excellent shape. I checked on KBB, and that's about what they say, too. I checked every option (leather, moonroof, etc) just to get the max amount, and it came up with:
Suggested Retail
Excellent (meaning basically mint)
$2,198
Private Party
Excellent (again, basically mint)
$1,648
Very Good (very, very few flaws)
$1,548
Good (what most cars fit into; pretty good for the most part, but needs a few odds and ends)
$1,498
Fair
$1,048
Yours would most likely go under Good Condition, which is where 54% of cars fall into. The miles are very low for the year, which is a big plus, and there's no rust or dents. However, the problem is we're talking about a 20 year old Pontiac, which means the major pluses don't really add much to the value of the car since the base value is starting so low to begin with. This is also reflected in how little difference there is from a total piece of crap example of this car, to an absolutely mint one ($600 separates a car that's barely drivable from one that looks like it rolled off the showroom floor). Even retail is not much more than the top private party value, which says a lot. Unless you're desperate for the money, you're probably best off keeping it, or maybe giving it to a relative/close friend for a first car.
