I did. I kept it for a good bit of time, sold it. Bought another (different color).
There is no redesign available for Pakistan or for that matter most of the countries.
As for charge and cost. I have never asked, since according to the service centers i used (expressway and Metropolis in Islamabad), they have never had a belt issue ever and they have serviced cards with 100K+ on the odometer. Could be because of our weather or a much much more frequent service interval here/ or our obsession with oil changes whether or not from official service centers, I really do not know.
The other countries which sells peugeot with a humid/ hot climate is Malaysia, SEA. You can check paultan for more info regarding timing belt issues (if it is there). They IIRC only get one trim (I could be wrong) which is extremely similar to our allure.
If you check out the dedicated 2008 thread, I have posted more stuff there including how to update the software of the infotainment unit (does nothing new) etc.
