Peter wants to sell one of his cars that has a diesel motor to his nephew Brett. Brett is eager to purchase the car but Brett does not realise that one of his uncles cars is diesel.

Peter writes a letter to Brett as follows:

Dear Brett,

I know that you are interested in buying one of my cars. I would like to give it to you but I know that you wont accept charity. Therefore I will offer it to you for $500 (I reckon it is worth about $2,000). If I dont hear from you by this Friday I take it that you are happy to buy it for $500. I will then drop off the car to your place on the weekend.

Regards,

Peter

Brett does not see the letter and there is no further communication between Peter and Brett.

On Saturday, Peter delivers the diesel motor car to Bretts home. Brett arrives home to discover the letter and the car from his uncle. Brett realises the car is diesel and he does not really want the car. However, Brett decides the car is still useful and starts driving the car to and from university. After three weeks driving the car Brett decides that he will return the car. He has not yet paid Peter any money. Peter thinks Brett is ungrateful and demands full payment.

Brett wants to return the motor car to his uncle. Peter is angry with his nephew and he demands payment for the car. Peter says he will lodge a small claim and sue Brett for the money. Brett states we are family and you cant sue me.

Explain whether the uncle/nephew relationship has any effect on whether or not there is a binding agreement. 6 marks)

On the same telephone call Brett also says to Peter that There is no contract because I never agreed to anything. Peter says Its a bit late to return the car now. Youve been driving it around.

Has Brett accepted an offer from Peter to purchase the motor car? (4 marks)

On the same telephone call Peter says that I was being nice to you and offering you the car at mates rates.

Could $500 be valid consideration for a contract to sell the diesel motor car? Explain why/why not? (4 marks)

Brett tells Peter on the same telephone call Even if you can convince the judge that there was an agreement, I can get out of it because I didnt know you had a diesel car and I never wanted a diesel car. I thought all your cars were petrol. Is it correct that Brett can avoid contractual obligations on the basis of his mistaken belief? Why/why not? (6 marks)
