A vehicle service contract from a reputable dealer or company is an excellent thing to buy. However, such contracts can be voided if the rules are not followed.

There is significant confusion out there about the difference between vehicle service contracts and auto warranties. The only similarity between the two contracts is that they both cover you from unforeseen mechanical breakdowns.
