I'm currently sharing a 2008 Toyota Camry 2.0L with my family here in Singapore. I've only recently started commute-cycling more but if I was to purchase another car in a few years time, it would cost something like this. Based on today's prices:
Toyota Yaris 1.5L (lowest end Toyota sedan)
Car cost: US$39,000
Certificate of Entitlement (COE) - lasts 10 years before expiry: US$51,000
Road Tax: US$550
Insurance (compulsory): $850
TOTAL: ~US$91,400 drive away
Standard unleaded petrol: US$7.20 /gal
Umm yeah, I think I'll stick with the Brompton after this car is scrapped.
