Those three year "national" warranties are only good for making the buyer feel warm and fuzzy at time of purchase. Once you start getting into the fine-print and the silly requirements and clauses, things go downhill from there pretty quickly
e.g. servicing requirements - any car over 10 years of age needs to be serviced every 3 months/5,000km, with proof sent within 7 days. Fine for a daily driven turbo car, silly for anything else (yeah some people may disagree, but overservicing is a waste of money, imo)
then there is the consequential damage clause. which in my mind goes something like this: you oil pump fails, and you pop the motor. they will fix the pump and you cough up for the motor, since its failed as a "consequence" of the oil pump blowing up. thus, many things end up in this grey area and you end up having to fight with them as just about any issue can be lumped into this "consequential" category
plus, repairs are only partially covered, and you pay an excess for the claims too. nice little scam in other words... had i known earlier, i would have had the warranty removed and made the price lower on my 35
