Hmm.. so it seems there arent too many Mehran's defenders here. Here goes.
safty,durability,economy,after sale,comfortability..gas n petrol consumption..peace of mind..
Safety: You want a serious answer right? Your safety is most definitely in the hands of God. Never forget to recite dua-e-safr even if you are driving a million dollar F1 car. Your safety mostly depends on how you drive.
Durability: Can't say for sure about the latest models. But lets compare a 1989 Mehran with a 2003 Santro. Mehran: no suspension work, original engine. Santro: New engine, new rear shocks.
Economy: Pretty good for an 800cc carby. On gas it runs and goes like a cd 70.
After Sale: Lets put it this way, Mehran is the queen of resale.
Comfort: I feel comfortable when my pockets are still warm with cash, that I would have spent had it been my Santro.
Gas and Petrol Consumption: Answered already.
Peace of Mind: It sure is a peace of mind. Mehran is definitely not the best looking, the best handling, the most comfortable or the most powerful car in the world but it certainly is a very reliable car in our conditions. I am more than happy with my 98. Don't ask about the Santro.
