My opinion is to forget the warranty and pay for any repairs if needed. At only 30K miles, I doubt anything expensive will happen for a while.
I don't have any experience with 3rd party warranties, but I hear a lot of stories that they like to deny coverage by calling everything a 'wear item'.
I have never bought an extended warranty on anything, and at age 75 the only major repair I have ever had to pay was on an 80's Dodge Minivan, $1700 to rebuild the transmission. I figure I'm many thousands of dollars ahead.
