Well am must be one of only a
few who can
HONESTLY talk about this subject ... qualifications if you like..
Owned - Z4 Black Roadster
Owned - Z4 Grey Roadster with Hardtop
Own - Z4 Coupe
Well Beedub is right when I purchased my hardtop I honestly felt it was the best of both world I just loved the look! ... but this is when I realise how much I liked the coupe ...and the lure of coupe ownership was too much for me and I purchased one.
I really enjoyed the roadster great on a summers day etc etc, but I feel the coupe is a step up IMO simply as there are not so many about , I must see 10 z4 roadsters a day on the M4 , and maybe 1 a week that’s a coupe. That what I personally love about the coupe and its stunning lines and I personally feel the rear is perfection.
I really cannot understand anyone who thinks the coupe is ugly as 80% of it looks like a roadster anyway??? And that person should consider changing their car as it obviously does not like 80% of theirs!

Without doubt the coupe is a special car, where as the roadster is “another” beautiful convertible
Either way the debates are fun, as being someone who has all 3 possibilities does make me smile.
