NSW Privately Sold Car - Refund issue

[Florian]

Hey all,

I bought a car 10 days ago from a private seller.
6 days (and less than 100km) after purchasing it the car broke down (gearbox) in the highway.
The mechanic ask me literally the price of the car in order to replace the entire gearbox (5500 AUD).

But the seller told me that the car is in good condition, and that he never had any issue with the car (I even got a text message...).

I can't afford the reparation. Is it "legally" possible to claim at least a partial refund from the owner ?

Thanks.

I just want to add that I just called the seller and he doesn't want to talk about any refund.
