Express Logistics Ltd, a haulage company based in Kaduna, purchased five heavy-duty delivery vans from Chukwuma Motors Ltd for N80,000,000 to expand its fleet. During negotiations, the Managing Director of Express Logistics Ltd informed Chukwuma Motors Ltd that the vans were required specifically for long-distance transport of refrigerated agricultural produce across rough northern terrain. Two weeks after delivery, the following issues emerged: 1. Two of the vans suffered persistent engine overheating and system failures when carrying refrigerated goods, rendering them completely unfit for long-distance haulage. 2. A third van was seized by Nigeria Customs Service because it had been unlawfully imported into Nigeria by a third party before Chukwuma Motors Ltd acquired it without paying custom duties. REQUIRED: (a) Advise Express Logistics Ltd on the implied conditions as to fitness for purpose and merchantable quality under the Sale of Goods Act 1893, citing relevant statutory provisions and decided cases.
