Firstly can I say what a fab site this is......my partner and I own 2 BMW's, 2007 2.0 Z4 and a 2010 320d M sport. We are both new to these cars and at the moment the Z4 has developed a rather strange noise from the intake manifold area ( see post ) but anyway, I am an electrical/mechanical field service engineer and my partner is a psychotherapist. We both enjoy driving and these cars loved to be driven, although mine ( 320d M sport ) is really good to drive, I find the Z4 a bit skittish tbh but none the less it is a great fun car to drive with the roof down. 

Hi Andy...welcome to the Forum!

It's good that you have both types of Beemer...hardtop and soft top...both are superb cars.

Do you have any pictures of them to post up on here?

Good luck with the Z4 repairs...let us know how you get on with it

Cheers,  Trevor
