The first thing that came to mind: Tell those importers in Cotonou that business just got better.
I just read that the federal government of Nigeria has just decided that buses and trucks imported into Nigeria must not be older than 10 and 15 years respectively. The age limit for imported cars had already been set at 8 years some years ago, and is not always being abided by – with many import vehicles having parts like alternators, engines, oil filters, in complete disrepair/useless state. An example inspected bus was inspected to have a 17-year-old oil filter, which is atrocious given that the best oil filter will only last 3-4 years on an actively used vehicle, especially a bus. In the report – at least the part I read in the newspaper – there was no mention of air pollution. The minister of trade and commerce, Charles Ugwu, said that it was to stop the ‘importation of vehicles that would require excessive maintainance’. Well, the real reason is not really that far-fetched: the announcement was made at a meeting with the local automotive manufacturers/assemblers and major importers/distributors. Remember, Nigeria has a history of import prohibition as a trade policy instrument.
