£15k sub 5s car with some comfort and has to be daily used?

[Mrinsignia]

As it says above, I am looking at various car options for £15k. I prefer some comfort and reliability, but 0-60mph in 5 secs and half decent round corners would be nice. Also prefer auto, but could go with manual for the right car. Any suggestions chaps? Ideally car would be a BMW m6 but the newer shape is outside of my budget... For now 🤔
