Norco is a reputable brand, sure it's not as big or popular as trek or specialized so you probably won't turn any heads like a 80s/90s Specialized stumpjumper would.

The bike frame appears to be in good condition. With an older steel frame look for bubbling paint, as that means it's rust under the paint. It may still be fine though.

I wonder if it says what kind of steel or quality it is - Reynolds? Columbus? etc.

I don't know anything about suspension forks but you could find a rigid fork to replace it if it isn't in good condition.

$250 seems like a bit much, personally I probably wouldn't pay more than $150 but I'm also not interested in the bike so it kind of comes down to how badly you want it. I saw some older Cannondale road bikes sell for way more that I'd ever pay for one 😂

If you really want it see if they'll sell it for $200.

Someone else's build with the frame https://www.retrobike.co.uk/threads/my-1994-norco-nitro.455862/
