u/Dry-Education-4950

Not sure if this is the right place to ask. I have a 2005 Trek 1000 (Discovery Channel edition). Aluminum frame with carbon fork. In decent condition. Used it as a commuter bike and raced on it college. It was wrecked in 2009 but was looked over by a bike shop mechanic who replaced the old drive train with updated mechanical Shimano 105 components. Saddle needs to be replaced due to wear and tear. I just really want to know how much I could get for it nowadays. I've got pictures but obviously not allowed to post on here. Any help is much appreciated.
