Yeah, haggling over used cars is dead and buried. The market doesn't accommodate it in a world where there's more demand for used than ever.

1. More people got priced out of new cars.

2. More people are driving their cars longer.

3. Caravana and other online predatory loan machines are outpaying dealerships for cars, and flipping them for nearly credit card level interest rates.

Also, us millennials don't want to deal with that shit anyway. List the price, keep it near KBB value and you have a deal.
