2006-GS430

I purchased a 2006 GS 430 in January 2007. It currently has 34K miles and I am looking for an extended warranty. The car is in great shape. I had new brakes installed as the dealer I purchased from decided they would paint the brake calipers silver and got paint on the pads....I had to get rid of the squeal each time the brakes were applied. Anyway - the car was purchased for my wife. Love the car...would like to know the best options for extended warranty. Any suggestions?
