Listen to a VW owner. I skipped the extended warranty on the most unreliable brand in the history of cars. My repair costs from year 5-7 are the following which starts 1 year later that yours since my initial warranty was 4 years (Thanks to truedelta.com for keeping track of this stuff

)
Mar 2007 86000km $210.00 Noise gets louder the faster you drive. Sounds like a helicopter in the distance. Passenger Front Wheel Bearing was issue.
Sep 2008 123000km $45.00 AM Radio reception poor. Replaced antenna at top of car. Radio now works.
Oct 2008 125000km $359.00 When coming to a stop, car began shuddering. Check engine light appeared. Symptoms would go away while driving and appear stopped at idle. Dealer replaced vacuum pump and associated hoses.
$615(taxes incl) total, it looks I have $1000 in my pocket. If your extended warranty includes a deductible, I'm even further ahead. There is always a chance you will have more repairs, but the odds are in your favour. Drivetrain is 5 years, battery stuff is covered, I wouldn't worry.
