Generally speaking, dealerships are required to provide a cooling-off period, which gives you a certain number of days to return the vehicle for any reason. This period may range from 3 to 7 days, depending on the dealer's policy. However, some dealerships may not offer a cooling-off period, or they may charge a restocking fee if you return the vehicle.
If you're buying a used car from a private seller, there is typically no cooling-off period. However, it's a good idea to include a provision in the bill of sale that allows you to return the vehicle for a full refund if it's not as advertised or has major mechanical problems.
Regardless of whether you're buying from a dealer or a private seller, it's essential to thoroughly inspect the vehicle before you complete the purchase. You should also get a vehicle history report to check for any hidden problems or outstanding recalls.
