So I sold my car through DoneDeal the weekend, and yesterday I get a text saying that there’s a problem with the car that will Cost €2000, I listed all known problems with the car I have nothing to hide, just the problem i did list turns out is a bigger issue unbeknownst to me or the new buyer who checked the car himself before buying, I told him i will buy the car back at full price he paid, he said he doesn’t want, wants to meet up and chat and come to a conclusion of paying half of the problem, this was a Romanian group of lads for even more context, don’t want them knocking at my door etc for unnecessary drama, what do I do?
