Fiona wishes to buy a new car on a sale and purchase agreement. She goes to Perodua Agent and Distributor showroom. When the agent hands over to her some relevant documents for her signature, she realizes that the document was printed in blue ink and comes with incomplete information.

Fiona comes to you for help. Advise Fiona whether the process for sale and purchase agreement is valid under the law. Further, what is the effect if she decided to continue with the contract even though she realizes there are uncertainties in that document?
