They offered Bodde a 2013 Audi S4 in exchange for his car - if he paid an additional $30,000 - but Bodde refused that offer.
The tribunal heard a subsequent meeting between Bodde and Giltrap degenerated into acrimony. In March, Giltrap told Bodde the car was fixed. It asked him to collect it and return his loan car. He did so on the basis that did not settle the matter.
Later that month, Giltrap's solicitors told Bodde the car dealer did not believe it had to refund the Audi's purchase price.
They said Giltrap already replaced the car's engine block but if Bodde was unhappy, Giltrap would buy the Audi for $70,000, which they said was its current value.
But that didn't wash with Bodde. He appealed to the tribunal, which last month found in his favour. It released its decision this month.
Bodde said he was grateful to friends, including car dealers, who advised him on mechanical issues and consumer rights. He said the decision to go to the tribunal was not taken lightly.
"The way I was treated was utterly unacceptable, which is why I took that stance," he told the Herald on Sunday.
A Giltrap general manger did not respond to interview requests.
Bodde said he had received his refund and returned the car.
