When I do eventually take the plunge?

[MarkZ4MC]

Sat on a pleasant Saturday afternoon reading through Grant's book.

When I do eventually take the plunge, I always planned to pick up the 4.3 due to the improved exhaust note. However, one or two options in the 4.7 model year have taken my fancy like, I'm embarrassed to say, the Emotional Control Unit which replaces the Volvo key.

So, that got me thinking (and please bear in mind that sound is far more important to me than the marginal power increase in the 4.7)... does the 4.3 really sound that much better than the 4.7?

Fwiw, I'd be looking to keep the exhaust stock and fuse 22 would be removed within 5 minutes of getting home.

Thanks for your help.
