if you have passion only for automobiles (or any other field) please do not enter this field. enter only if you have passion+detailed insight of mechanical/body/documentation of a vehicle and have good eagle-eyes to detect inherent issues in a car. this work is excellent and can earn you a good income on a regular basis. my experience is that to buy a market car only, color matters ALOT, a good condition car always attracts a buyer, there is always a room of +20-40k above your purchase price if the vehicle is good in all aspects. my advice is to find a Mehran 2013-2015 model in good condition and try selling it for a 20-25k profit - give it some time and believe me 1 buyer will land at your doorstep to buy it at your price. this will boost your confidence and will teach you a good lesson regarding this field. in the end, yes, our own small setup to earn a halal livelihood is always better than being a top executive of a MNC as you are a 'naukar'. this is my advice for you.
