Nothing related to mechanical. Problems faced in importing, reselling, tax hikes, anything related to vehicle industry. It's suppose to be specific like cars or could give a range such as vehicles under the capacity of 2500cc draw a confined area to research on since vehicle industry per se would be too large to be researched within a constrained time period. Again this would depend on the problem. The reach could be extended for a problem like a discussion on the present tax issue at hand.
