The Z4 is suprisingly reasonable for a BMW running cost wise. Provided nothing goes wrong, its relatively light weight (1300kgish) means its suprisingly economical - probably as much if not more so than the S2000 - and it's also pretty quick as well (0-60 is 5.9 seconds). The engine itself is reliable, the major reliability flaw is the roof motor which, due to a design flaw, fills with water. It's probably the only £1k bill you can get on a Z4.
Contrary to the above I don't think you need to get one 'loaded with kit'. The Z4 is hardly the sort of car you'll want to use for long trips anyway, its a sunny day roof down sports car therefore things like integrated navigation are less important than they would be in a 3 Series or a 5 Series. The main benefit of the Nav is the way it allows excellent ipod integration - unlike an E39/E46 it doesn't make the interior look any better as it has a foldout screen not a dash mounted screen - and as a system its a decade old and interface wise certainly looks it. Its a nice bonus to have but it isn't a deal breaker.
The 3.0i Z4 is generously equipped as standard - electric leather memory seats and climate control are standard fit. Xenons are nice to have but as the 3.0i Z4 has projector headlights and a headlight washer system a good aftermarket install is inexpensive and effective.
I picked one up 4 years ago for my parents and other than a failed roof motor it has actually been very reliable. It suffered from the common cracked springs issue just before it was purchased and has been good ever since. Servicing is reasonable - its last service was an Inspection 1 at £229. Tyres are 180 quid for the back and 130 quid for the front.
Whats bad? Well the interior is fairly cheap and nasty and it isn't exactly a pleasant place when its raining or when you've got a long trip to make. The steering is a real shame - it lets the car down unfortunately. It has electric power steering with next to no feel. The stereing in my E39 is miles better which is quite sad really, as the sports car of the range it should be the other way round! The ride quality is a bit harsh as well - so much so that when pushing on along bumpy B roads it knocks your confidence the way it bounces around, it could do with a more compliant suspension setup. It is even worse with the standard runflat tyres which you'd be very very very well placed to bin.

and wait for the tyres to wear to a point where I can validate buying a set of non runflats. I'm probably going to go for a set of Goodyear AS2s at the massive sum of £104 per corner.
