Boss, you are buying your first car, so i would suggest to go for bravo because:
1) Please consider mehran an obsolete car now as the world is moving towards new tech.
2) Bravo has lot more options than a mehran, the plus point is that mechanically the engine is similar so u wont have problems.
3) it will be your first car so you will enjoy the mazey of a brand new car
4) People are still curioius about BRAVO so many ppl will ask about its details and performance etc....is ka apna maza hai. When ppl stop by and ask yarr kaise gari hai chalne, options, etc etc
OR if u have budget, u can go for any japanese car and enjoy.
