Warranty

In most cases, this warranty covers the transmission, engine and all related moving parts like CV joints, drive axle and timing belt. Some dealers will also toss in air bags and seat belts.

This warranty covers any part of the vehicle not protected by other warranties. Parts generally include audio systems, major electrical components and air conditioning. Be sure to check with your dealer for exact specifications. This warranty is also known as "New Car," "Factory Coverage" or "Premier Plus."

This is the most comprehensive out of all warranties. It covers many major parts and often includes roadside assistance, towing, rental car reimbursement and common wear and tear. Despite the name, however, it does not cover all components. Be sure to read the fine print before signing.

This is a good alternative to a full coverage policy, protecting designated components at a good price. Make sure you know exactly what the warranty covers before you sign.
