I used this car every day without any issues. About four months ago the engine started using a little oil, so I occasionally topped it up, but the car always drove perfectly. A couple of days ago the check engine light came on and the car lost a bit of power, although it was still driving normally no misfires, no unusual noises. I took it for a diagnostic scan and was told that cylinder 3 wasn't working properly, which triggered the warning light. All the spark plugs were replaced, and after that the engine started misfiring badly and the car now barely moves. The old plugs were put back in, but the problem remained. The scanner no longer shows a clear fault. I don't have time to repair it, so I'm selling it as it is. Apart from this issue, the car has always been very economical and it comes with a high-spec trim
