I know you can do what you want.......BUT
Ego? Greed? Stupidity? Total case of " fu**edupiness"?
Sometimes a seller could price a $10000 car for $100 and 99% of the lookers would offer $75!
Or tell the potential buyer tells the seller why his paint job is not perfect on the $4000 car for sale, and bitches that he did not spend $8000 on the paint job so it would be perfect!!??
