The warranty can cover little things that can add up real fast.. I took my car in to have my clutch replaced, and it turned out the flywheel needed replacing too.. the flywheel was covered under warranty, and so was the labor involved with it, so I paid $0 labor to have the clutch installed... the insurance company cut me a check for $1250 for that... I paid $2000 for a 4 extra year, 90k TVM warranty
