I've had things on Craigslist at a fair price had no takers friend of mine told me to bump the price up a couple hundred bucks
Bumping the price on this bike will not have the effect you want. Its just overpriced. I would list for $2K.
Thomas has it right. This bike is old but no super collectable so thus leaving it to buyers who are looking for something to learn on but not wanting to spend $3k on a 45 year old bike.
