Thanks Bhavna, cars are a big deal in Libreville. Sadly, the government has some restrictions in place that, may discourage you and may cause you to do a rethink severally before you may decide to wait and go with the taxi cab or taxi bus services.
Buying in Libreville may cost much more, importation may be a daredevil stunt as, you may get your vehicle impounded for jot meeting one of the extremely difficult and expensive factors listed.
Or, you just wait to buy from a friend who may be leaving the country.
Whatever you do, keep those fingers crossed.
