I got mine through Auto Warranty Broker (Insured Extended Car Warranties by Auto Warranty Broker
) and it's covered by Mercury Insurance. Initially I was going to go through the one recommended by the dealer but it was about $3K. This one came to about $1,800 with $300 down deposit and 15 credit card installments if I'm not mistaken. I've already had 2 claims (bushings and ac compressor) and they've come through fine.
Btw, does this '06 already have more than 50k miles? If not you should still be covered by factory warranty.
