Vehicle trade-in vs private sale is a simple decision that affects net proceeds. Private sales typically fetch higher prices but require more effort; trade-ins are fast and can reduce sales tax in some jurisdictions because the dealer applies the trade-in value against purchase. When you plan to move from one milestone to another (trade-in an older car to buy a newer one), estimate net proceeds under both options and include time cost and convenience. The question assesses the common-sense trade-off between speed and net proceeds.
