Sporty coupe under 50k AU(35k USD)

Hi, moved to Australia recently. Have been a car enthusiast for long, so want to get a really nice car that puts a smile on my face every time. It’s just me and my partner at the moment so don’t need rear seats but would like to have enough space to throw a couple bags for a trip or grocery runs.

I really like the idea of two door coupes and would ideally want something in that segment. But open to suggestions.

I test drove a Mazda MX-5, a Subaru BRZ and a used BMW 230i M. And quite frankly all three were so better than my previous car(an i20) that I was happy just driving them for the 10 mins that I did.

What would you advise me to get? My shortlist is:

1. GR86/BRZ
2. Nissan 370z/Z
3. BMW M240i (will have to extend my budget a lot)
4. Mustang GT

What would you guys advise? Please recommend any other car if you think should be on my list.
