perhaps a better q is what's the average cost for common repairs past the warranty period...say <100K miles
cooling system repairs
figure/estimate that versus the cost of a warranty to cover said repairs might help sway one person to or away from purchasing an extended warranty...it's all a crap shoot...those that have had warranty work needed past the standard time frame and had the extended warranty would say it's worth it perhaps...those that don't have an extended warranty and haven't needed one will say it's a unnecessary expense...
