Once "Broken" Twice Shy
We didn't buy the extended warranty on the 99, and one month 3 days after the warranty ran out, so did the vacuum pump to the tune of $1,700.
For the 03 we bought the 7 year 70k warranty for about $1500 negotiated at the time of sale, that covers about 90% of the vehicle.
The Piece of mind is worth it to us alone.
Also add us to the voices that have heard/read from several sources the inadequacies of non dealer warranties.
