[DiDelaney]

Here are the precautions for trading in an old car at a 4S store: 1. Check if the procedures are complete: Before going to the 4S store for a trade-in evaluation, first check the vehicle's documentation. 2. Prepare a temporary replacement car: Generally, trading in an old car takes about 2 weeks. If you cannot be without a car, you need to make preparations. 3. Understand the vehicle price in advance: You can check the price of used cars online, in the used car market, or at professional used car brokerage companies and 4S stores.
