Thus, it is not advisable to use log sheets and seat belts to confirm the year of manufacture, as, for instance, log sheets give only the date of first registration, not the date of manufacture. In plenty of time ato export companies provide its clients with all necessary documents, which give full information on the vehicles. Please, also note that in Ghana vehicles attract overage penalty, when they are more than 10 years old.

In addition, all vehicles are categorized by the following categories, determining the duty amount to be paid:

engine capacity e.g. 1.6cc, 2.0cc, 2.5cc, etc.

usage/purpose e.g. buses, trucks, lorries etc.
