It's like buying any insurance, It's hard to tell if you need it or not at
front.  If you decide to get one, make sure to get the extended warranty
from manufacture (VW) directly.  I heard so many independent insurance
companies went out of business after several years (when insured cars are
getting old and having major problems)...
