Once your car has left the dealership, it loses it's value but if you need repair work after your car warranty has expired, you're usually in for surprisingly high repair/replacement costs. In this economy, it may not be possible to pay for the work without an extended warranty.
Are you locked out of your car? Do you need to be towed? Do you have a flat tire that you can't change? Has your battery died and left you stranded? If this sounds like you, then now is the time to look into the coverage provided by an auto warranty that helps you through these difficult situations.
