Agree with F1, the large pricing gap fom the Msia side is for
you to makan more commission, they in Msia cost lower than us mah,
so they give you a good price, you can mark up and earn the
rest! 
Limo want to do $30 or $35 not because they want to do, they got
no jobs and are squeezed by the big boys like Imperial, Royal, C
& P. they must be able to tahan lah for long lah... After some
time, hey will know that they not making much from those rates
lah...
As for me, $35 I do, if St Regis to ION or Orchard Mandarin, $35
can do mah! Cannot meh? Less than 10 mins job, can... Y
not??? 
Lor maybe MBS to Swissotel or Suntec, $35 can also leh... Still
good leh...
