Hello there, I am currently a student and I bought a 2001 Fiat Punto Mia (MK2) with 74K miles on the clock from a trader to get me from my place of work whilst on placement, it cost me £620. The difficulty I am in is that the dealer in question sold me it from his private residence, however, he told me throughout the viewing of the said car that he was a trader, and that he occasionally brought vehicles back to his residence to sell, he had even filed out the registration documents as a trader. 5 weeks after buying said vehicle the car has developed what looks like a serious fault, in that the cylinder head gasket has possibly been banjaxed. I was driving home from work yesterday, and the temperature warning light came on. I pulled to the side of the road, and opened the bonnet to check the water level of the cooling system. There was an acceptable amount of water in the filling point, I topped it up anyways, and revved the engine to get any air pockets out, and then topped it up again. However, whilst driving it the rest of the way home, I soon found the temperature warning light on again. At home I plugged an OBT2 diagnostics adapter into the car and revved it up again, the thermostat opened and the radiator's fan started spinning, however the temperature kept climbing (up to around 120 degrees c), the warning light ignited again, I was getting no heat out of the internal heating fans, and the heating pipes running into the radiator were still cool, even though the thermostat was open, the water in the filling point was also bubbling and coming back out due to back pressure, I even got out of the car and used a laser temperature gauge on the engine bay, and it was reading 117 degrees c, the car had also lost a bit more water prior to my parking the car in the driveway. I was under the impression I had bought it off a dealer, so I phoned him and told him the problem and asked him to either take it back or repair it. He refused, stating that he was a private seller and that he had sold it as such, and due to the car being over 6 years old I had no warranty. I told him that he had told me he was a trader and had filled out the registration documents as such, but he was having none of it. I couldn't do any more about it at that point over the phone, so I told him he would be hearing from me again, and he then hung up the phone. I then googled his mobile number on facebook, and lo and behold I found the business that he trades under, further googling got me the address of the said business, which I have recorded. I then phoned the DVLA to ascertain whether the previous owner of the vehicle was the dealer in question, they confirmed this, I asked them whether the car had been owned by a trader prior to my registering it in my name, they said yes, but they couldn't give me the name, I then asked them was it under the trade name I had found, they said yes, so as far as myself and the DVLA are concerned I bought the car from a dealer. Therefore I can assume I'm covered by the trader's section of the sales of goods act. Further googling also showed me previous adverts the seller had been posting on the likes of gumtree, I even have a cached copy of the advert for the car I now own. I then contacted the consumer advice line, needless to say they weren't very pleasant, and the person I was talking to basically told me that their main concern was that the trader I had bought from was trying to pass himself off as a private seller, and that if I wanted to get compensation from the likes of a small claims court, I should've bought a more expensive newer car (bit impossible considering I'm a student). Considering what I have said above, could anyone please tell me what my options are in this case? Cheers, Splat.
