Im thinking worst case scenario the lowest we could go is 5,000 even

IS this price fair enough on my end but at the same time enough to attract buyers?

Reason i ask this was cause when i posted my M3 for sale i had sold it without an engine and on the ad i posted the car being a car for someone who is willing to make this car into a project car or track car. Sure enough I sold the vehicle to someone who wanted to make a project car out of my M3. I based the price on the NADA value if i had sold it in running conditions. I didnt want to low ball the price on my end, but i also wanted to attract customers would be willing to buy at the asking price. I even broke it down to the buyer of how much it were to sell and why i was selling at the price that i gave. Funny thing is the buyer wanted 4,000 for my m3 and then i told him that i would not budge and that i would stick at 5k, and then i told him how much it would cost for a new engine and installation and said that if he were to buy another car as mines he'd still shell out alot more because he would not be able to get the final price of a working m3. Sure enough he realised that my asking price was within reason.
