I think Daihatsu Sirion is using the same chasis as the Perodua Myvi. That model had a back order of 7 months last year - very popular in KL, Malaysia.
I might want to look at the Lancer Sports model. It looks really good.
By the way, I'm not married yet, so, not much financial commitment. Just that I don't like getting into too much debt and also, I would like some spare cash to enjoy - no point getting an expensive car and u dun have spare to do other stuffs

Running cost (installment + petrol + carpark + insurance + misc) around SGD500/month possible?
If Lancer Sports, would it be about SGD1000/month?
Say, Monday to Friday travelling from Boon Lay to Toa Payoh for work.
