Thanks for the reply!
When he asked if it came with a rwc he was told no. He then asked if he was to pay extra for the car if one could be supplied, he was told no as the guy didn’t have the time to organise one. He then asked if it needed anything done to pass a roadworthy and was told there was nothing much that needed to be done and that it was in very good condition. These conversations were all via text message which he still has. He has text the guy to inform him of what he was told by the mechanic and to ask if he knew about the issues and of course he has no reply.
Thanks Di, glad to hear he has some type of correspondence to hand. If it were me I would take the following course of action, please note I am not offering advice on the particular circumstances your nieces boyfriend has found himself him, merely some information which may give you some ideas on where to go from here. I would: (1) Attempt to call the person who I purchased the car from to discuss the issues. (2) If he won't answer I would visit the location where I purchased to car (unless the person posed a particular threat etc.) (3) If he is unwilling to make good the issues, based on the information to hand, I would send a letter demanding a refund, (4) Failing that I would send a second letter with notice that a failure to 'come to the table' will see proceedings commenced in the Magistrates Court of WA (We don't have VCAT (or similar) in WA, but they might be able to assist, you will need to check this with them) (5) Commence the claim on the basis the seller was asked about the issues affecting the road worthiness of the vehicle at the time of purchase and made, what appears to be from your comments, misleading comments relating to the condition of the vehicle, which ultimately seen 'me' purchase a defective vehicle.
Basically it needs to be demonstrated that proper enquiries were made - the Court (or VCAT) won't compensate the negligent or someone who just didn't make proper enquiries, however if it can be proved that the seller knew, or ought to have known, about the issues with the car, and didn't disclose them, you're in with a good shot. Although, I stress that by no means is it certain that the matter would be found in favour of the purchaser.
Best of luck.
