There are no 'dud' cars on the roads in Singapore. The line-up in the photo shows the typical kinds of vehicles everywhere - they are always immaculate and clean. Cars are a status symbol, and people will have big mortgages to own one - even the young people. Because apartments are small, people are more likely to be 'seen' in their car than in their home - hence the importance of their vehicle.
Taxis, on the other hand, are much more 'typical-looking' as in the photo, and of course there are thousands of these.
You do see open-back trucks carrying workers to and from work - usually without seatbelts. But you have to look pretty hard to see a plain old private vehicle anywhere - they all seem very swish!
