Narrowed it down to these three.

About 18k on the black- if you are going to finance through them then u can get a smaller GFV or less interest. Good luck,, if you are paying full cash abotu 18k but maybe if you like it and if tyres are very good get a deal on servicing etx which is always worth it. cheers

I have to agree with others, I'd go with the black one

I think they're all over priced, but I would personally go for the blue one if I could get them to knock off around £700+.

+1 get it cheaper as less mileage and hardtop not needed with a Z4. I'm on my second now and first one came with one which was a pain to shift as they leak so persoanlly just save the money upfront - if you dont ask you dont get!

All 'look' good to me but the test is a visual inspection and thorough check. If you've got cash then time to offer silly money for the one of your choice and see what happens. good luck.
