QUESTION THREE Jabir decides to sell his car and places an advertisement in a local newspaper on Monday stating: 'Ford 2018 model car for sale - RF 80000/- for a quick sale.' He also gave his contact details. Ali viewed the car on Tuesday and said he would pay RF 78000/- and said Jabir must let him know by Friday if that was not agreeable. On Wednesday Suma viewed the car and later that day she posted a letter stating that she agrees to buy the car for RF 80000/-. On Thursday Jabir received Suma's letter and sent a letter in reply saying he would sell it to Suma for RF 80000/-. On Friday Aisha viewed the car on Jabir's driveway and posted a note through his letterbox saying 'the car is ideal for what I want and I enclose a cheque for RF 80000/. I will collect it tomorrow'. On Saturday Ali phoned Jabir to arrange his collection of the car and payment of RF 78000/. The same day Suma phoned Jabir to say she could not pay RF 80000/- for the car. Jabir seeks your advice on whether he have formed a valid contract to sell his car with any of the parties?
