How much is my car worth?

If I want to personally sell my Honda Civic I would like to know if anyone could tell me a good price to ask for it. I heard their value is extremely high but IDK. Its a 1997 4 door. It has a small dent in the penger side door and the back seat is kinda torn. But its a 5 speed manual. And it has a brand new engine only 1 year old. If you have experience with trade ins I really hope you can help. Except for those miner issues the car is in great condition and very reliable with automatic windows doors. a cd player, cette player. and it has front air bags. Please help
