That's a really long wall of text, so I'll sum it up for you. The owner of a 2011 Mercedes Viano was denied a HDB Multi-Storey Car Park season parking with the main reason being the excessive weight (more than 2,000kg) of the vehicle.
So what does he do?
He proceeded to spend some time checking out the various cars parked in HDB MSCP and came up with a short list of cars that weigh more than 2,000kg.
If you look at this excerpt from HDB's website regarding the parking restrictions for commercial vehicles (the Mercedes Viano is predominantly used as commercial passenger buses), it is a straightforward rule that commercial vehicles parking in a sheltered car park must not exceed 2,000kg.
With the rationale behind it being safety and environmental concerns as well as "efforts to preserve the character and ambience of residential estates"... Hmm, maybe HDB just find the Viano too ugly to be parked in a housing estate?
In all seriousness though, this netizen has a point, this issue likely stemmed from outdated regulations. These regulations were probably established back when commercial vehicles weighing more than 2,000kg are agricultural behemoths.
Maybe HDB should look into updating its regulations? in the meantime, I suppose this guy should get rid of the Viano and get something else, like one of the cars he mentioned instead?
