Not having a pricing strategy
For example, you want $10,000 for your used car. You have determined that this is a fair price, halfway between the wholesale and retail price estimates for a vehicle such as yours. So, you ask for $10,000 in your advertising.
But, what do you do if a serious buyer offers $9,000? Should you have initially asked for $11,000? Or, should you hold firm at $10,000? What about countering with $9,500?
Think about these scenarios before you offer your car for sale!
