A quick search brings up a blue book estimate.I rated it at the bottom tier, because it will need a new battery.

Nice looking bike. It's better, in my opinion, than a modern ebike because it's based on a light trek frame. All it needs a a new battery, which will have to be a third party battery. I'd give 200 bucks for it. I'd spend $100 on new electronics. and $#200-400 for a battery,
