Bought a second hand car from a well-known car dealer ship. After a week the engine warning light came on so phoned the company to try and sort it. After a month or so of phone calls they finally got down to having a look at it. They have now said the engine is knackered and that I should look on their website for another car but theirs nothing similar. Do they have to offer me a like for like car. I can also see it being a nightmare trying to get my money back. Any advice would be great.
