Who is Roger?
Almost 1 in 2 used cars sold by dealers develop a fault within a year. There’s little advice out there on how to avoid it—especially for non-car people.
Roger started Secondhand Hero to tell it like it is and help buyers without the hidden agenda. In 2017, he bought a lemon that cost him $14,000. Since then, he’s obsessed with what makes a used car worth owning—and helped dozens of buyers find proven reliable cars. He holds a Master of Engineering from UNSW.

Darvy - 2018 Mazda 3, $14,000
