This is a sturdy, inexpensive mountain bike that should be good for several years of riding. The components are nothing special, just servicable. It should be great for casual trail riding. If you get into racing or taking long rides, you’ll probably want to upgrade.
Brand new, this bicycle probably cost $400-$500. You don’t mention what condition it is in, how it has been serviced or how many folks have owned it. Still I might venture it is worth $100-300.

Hope this helps you out.
It depends on what you are looking for. It is considered a higher-end entry level mountain bike. It probably retailed new around 500-600 dollars. I’m guessing the bike is at least 4-5 years old, so I would only pay 50-150 dollars depending on condition. This bike will handle pretty much any trail you go on. It is a very sturdy and solid bike. The only negative thing that I noticed was that the fork was very stiff. I’m a fairly heavy rider (220lbs) and still rarely got full travel out of the fork. Not the smoothest of rides. All in all though, a good entry-level bike.
If used, I would suggest having the bike looked over by a bike shop to see how much money would be required for general maintenance. If you need a new chain, cassette, chain rings, cables, brakes, etc. you might be better off buying a new bike. or paying only 50 bucks for it.
