Hi All, Am trying to get opinions from members on the car issue am currently having. On 14th December 2013, I bought 2003 reg Peugeot 307 1.6L with 101,200 miles on the clock for £1,000 from a car dealer. I saw the car on Autotrader. It fitted what I wanted in terms of look and price. I test drove the car and was satisfied with the drive. I paid with my credit card and took car home. The car came with 3 months warranty for maximum repair worth £200 with Halfords. For me this was only an extra, as I would still have bought the car even if it didn't come with any warranty. On the 28th of December, on a very cold morning I started the car but it didn't start as smoothly as it used to. It then gave me Catalyst converter and anti-pollution fault. When it started it was misfiring, but everything returned to normal when the car was warm enough. I googled the issue and found it was a common issue with Peugeot cars. I had planned fixing the problem myself as soon as I had the time to do so. On 3rd January 2014, another cold morning, I started the car but it won't start. I called AA, and the rep examined the car and concluded that the head gasket was probably the issue and advised I take it back to the trader, as it had warranty on it. I decided not to take it to the trader, but to take it to Halfords who are the authorised auto centre for the dealer. The guys diagnosed the issue and called me to say it was bad news. They confirmed the head gasket was gone, and that it would cost me £900 to repair. They said that it wasn't worth the effort, seeing that I only just bought the car (done 336 miles as at now), and for only £1000, and advised I go back to the car dealer to let them aware. I have now written to the car dealer informing them of the incident, stating that under the Sale of Goods Act and in line with Reverse Burden of Proof, have asked them to either repair or replace the vehicle. The letter was sent today by Special Delivery. I believe the dealer was aware of the problem before the car was sold to me. They told me at the time of purchase that car only arrived as part ex. From my experience, before car traders P/X cars, they thoroughly examine cars to ascertain if any underlying issues exist, and based on that arrive at a figure they are willing to P/X the car for. Anyway, that's by the way. Considering the fact that it is still 3 weeks since car was purchased, I feel I have a case for the trader to repair or replace the car. I am not really interested in a refund unless it is absolutely the last resort. I just want the head gasket replaced. Any advise from members? Adojay
