M4 would be too much money I'm afraid!
The deal I got was pretty good - M-Sport plus = 19" Bicolour Orbit Grey 704 M double-spoke wheels, Loudspeaker system - harman/kardon surround sound, Sun protection glass, High-beam Assistant, M Sport braking system, Adaptive LED headlights together with Apple CarPlay etc - for < £35,000 which I'm very happy with.
