Alikhan and toofast are both indians with inferiority complexes pretending to be pakistani just so they can put down Revo. Ignore them both. Revo is a Pakistani designed car, there is no evidence that suggests otherwise. Unless you count a pair of headlights.
Okay...i'm comparing the 800cc with mehran, 1000 with alto.
Price:
Revo is by far cheaper, nearly 100,000. You can even buy a CNG fitted Revo for less than a standard Mehran or Alto.
Plus although its a privately owned car, I heard that banks are going to help revo by giving soft finance deals to help people buy Revos.

Design:
Now this is purely subjective and depends on your own taste. I personally think they are all okay, with the expection of Mehran. I'd probably rate Alto above Revo, but not by much.
Power:
Revo 800cc: 35kw
Mehran: 29.4kw
Revo 1000cc: 56kw
Alto: 55kw
Revo has more power than both suzukis, especially more than the Mehran. This isn't a suprise, because everyone knows suzuki under power their cars.
We don't know the weights of cars so we can do a power/weight comparison, but all cars are roughly similar in size, and its not like suzuki engineers use lightweight aluminium/titanium material. Revo probably will win on that count as well.
Country:
People have said Japan makes better engines than China, thats definitely true comparing Toyota or honda with china, but not Suzuki. They are the worst Japanese car manufacturers in terms of quality, and the suzukis they sell in Pakistan are notoriously appauling. If you buy Revo, well its quality can't be assured, but at least it can't be as bad as the build quality of the mehran, which just fall apart. I once sat on the bonnet of a mehran, and it left a dent! What a joke.
So if you were chosing between Revo and Mehran, I'd say get Revo. If you wanted an Alto, then think of the 1000cc as a cheaper version of the Alto.
Revo is overall a much better car than the Mehran, on all counts. There's not a single advantage of the Mehran over the Revo, not a single one. Granted Alto is a different story, but it isn't as popular as the Mehran.
I'm still suprised some Pakistanis here are so fast to put down a Pakistnai car, the people behind it are Pakistanis like you and me who are fed up with Suzukis domination of Pakistan's industry and are giving us the chance to replace it with a Pakistani version. Suzuki have ripped of Pakistani consumers and its about time someones come along to get rid of them.
