Final answer:
True, warranties or service contracts must be included with the vehicle on the purchase contract and be available for the customer to view, with copies provided upon delivery.
Step-by-step explanation:
The statement that any warranty or service contract must be included with the vehicle on the purchase contract is generally true. The consumer should be able to review these documents upon purchase, and copies should be provided at the time of delivery. Warranties are assurances from sellers that they will fix or replace an item within a certain period if necessary. A service contract, on the other hand, often requires an additional fee and extends the guarantee that the seller will address any issues for a set period. These are common practices, especially for significant investments like cars, appliances, and houses.
