are you talking about the 2011 model that first came out in china?.i dont know how they planned to introduce this model in pakistan in 2009 two years before its international release.hopefully they will release the new model by this time next year.
if im driving and i get into an accident id rather be in a 25 year old accord then a new mehran.
its up to you if you like the car and are satisfied with the condition to pay alittle extra then the budget you set, however you mentioned the car is in reasonable condition then maybe you should look around to find a car in good condition and then spend the extra buck.if you are buying any 6 year old car you buy something in good condition that does not require much work otherwise in six months you be selling the same car.
