Looking for one of these and have a few quick questions:

Do they have paddleshift on the autos or are they all 'button shift'? (Need auto due to motorway commute)

Autotrader shows all 35iS models as the same bhp as the std 30iS (306bhp) but aren't they 335bhp?

Anything else I need to look for, avoid, etc?

I think the Z4 E89 35i is 306bhp and the 35is is 340.

Plenty of friendly help here http://www.z4-forum.com/forum/viewforum.php?f=23

ETA I think they both had the 7sp DCT, which had paddles. The 6sp auto was only available on the 3.0.

Having got a 3.0 (E85) Z4 and had a 235i, I can see why people prefer the NA delivery, even though it's less powerful. I'd certainly consider it..

I've had two Z4 35iS's ... but have driven the 35i.

I would go with a 35iS as it has more as standard from what I recall and aside from the extra power (which IMO is noticeable higher up the rev range) you get a BMW sports exhaust as standard. The burbling, popping and bangs on over run in sports mode is awesome and far better than a lot of the cars these days that have it mapped in specifically (like the A45 I had).

It is an awesome car and if I hadn't of wanted a bit more space with rear seats I would still have mine.

The 35iS is DCT (as in like DSG) but the 35i can be had as a manual.

Adaptive suspension is standard on the 35iS and many are highly spec'd.

The multi speaker surround system is awesome and a polar opposite to the standard system which is exceptionally poor, even by BMW standards !

Is there anything apart from the usual things I need to look out for? For example big services/cambelt changes?

I have an E86 Z4 (so the 3 litre N52 engine that is also used in the E89 3.0is-drive).

So I'm not too on top of the 35i and 35is, except that they both use the twin-turbo engine (N54 I think) that was used in the first E9* 335is and 135iM. But the 35is gets a slightly higher state of tune than the 35i, but both can be mapped for more anyway!

The 35i came as a manual with an auto option, whereas 35is was auto only and had adaptive suspension (which was an option on the 35i). People seem to really rate it, but if it wears out I've seen £600 a corner quoted for replacement so depending on the age you are looking at you may need to factor that potential cost in!

None of these engines uses a cam-belt thankfully!

But you could find out loads more if you were to head over to Z4Forum.com - good luck! thumbup
