since i am a new user to car and i just purchase mehran vx euro 2.i am not aware about the performance of other cars so unable to compare but i can share my experience and statistics about EFI mehran. fuel average is 20 km per litter on long rout. i have ran it 1400 km and in city it is about 14km per litter. engine dont heat up as i heard about this problem from many people who used old mehran. still i did not installed AC so can not comment on it. i felt its brakes are not good they should be more improved. i will share the statistics when i will used and installed the ac in it. till now i am enjoying it. sound of engine is less now and smooth as well. pick is good as it is on petrol. i drive it on 120 speed on long rout but on that its road grip is very poor so its good to drive on 85 and 90.
