Yesterday I spotted a brand unregistered new white taxi, from afar along PIE from Jurong towards Bukit Batok Exit. From far, the rear dont look like any taxi I've seen, so I speed up to take a closer look and hey, its a Hyundai Azera!
Looks Like the cab company is finding creative ways to save money(or earn money) by buying much cheaper alternatives to the usual Mercs.
See if they charge the taxi drivers the same/similar rental rates. If they do, confirm earn more money.
