Yup, people keep trotting out the same stories - all UK cars are rusty because of salt, all Singapore have electrical issues, all Japanese have been stuck in traffic all their life, etc. etc.
Treat every car on it's merits, check for known issues, every car / owner / history is different. Take the car for how it actually is, not how all the sooth sayers on the Internets suggest it will be.
As for NZ New being a bonus hmm, not so sure on that one.
