You can try cartrade or Naza. Used Mini One, Cooper or Cooper S are quite hard to come by and any that comes on the market get sold quite quickly. Try the AB approved used car section at the Sg Besi outlet.
I've been to Pasar Road a few times but still very unsure on where to get raw materials to DIY, especially LEDs and stuff. Unfortunately, most of the time i will end up in the market behind or at Pudu...
