Best car to learn on is FX. I learned on my FX and still have the car and its in excellent condition even after 19 years. I have had it for 17 years.
It is lot more forgiving & tolerant for rough use than a Mehran. The under side of FX is much more sturdier and durable than Mehran. Excellent steering and handling. Much more stable ride on higher speeds (80KM+) than Mehran.
Maintenance is even cheaper than Mehran. Doesn't go out of tuning easily. A lot more foregiving on wrong gear selection than Mehran.
I know, because my Father has a 96-Mehran. Only 57K km on it.
Fx is still my car of choice, even though I am driving a brand new Cultus these days (only 16 days old).
