hello sifu zenix, and/or other sifus in this forum,

i am faced with a with big decision at this time, so looking for as much help and guidance as possible.

i have a budget of around 90k. in my mind, i am thinking of going for a little prestige, go for a used/recond mercedes (have not driven a merc before in my life).

searched online and found that for my budget, some B class B170 came up in the search. an example is this : http://www.mudah.my/Mercedes+Benz+B170+SE+...1152.htm?last=1

any comments on this B class ? it seems not a lot seen on the road. will it be a good buy ?
this one is 2009 facelift version, with parking assist.
how is the reliability ? i hear that for used mercedes, you may get hit with big repair bill for gearbox...

any other options for my budget ?

should i just forget about getting a used mercedes, just go for a new VW Polo Sedan instead...

quite pening liao, please help...
