M135i or GT86?

[57powell]

Hi all, long time lurker on pistonheads forums... Thinking about buying a new car soon and with around £21,000 to spend it's between a used M135i or a nearly new GT86...

Leaning towards the GT86 because practicality is not a huge issue for me and it seems like it will be cheaper to run as a daily, whilst also enabling plenty of sideways fun...

Know there's a lot of strong opinions on both cars so thought it would be interesting to hear some different (im sure reasonable and not at all biased lol) opinions on this.
