I own a 3.0, manual and had a 3.2 Boxster S for a couple of years from new.
When I purchased the Z4 I had no idea how good it was, it has exceeded my expectations. IMO it is not as precise in terms of handling and steering as the Boxster but the difference is quite marginal in day to day driving. My choice was either an older Boxster with a high mileage or a newer Z4 with a lower mileage. In the end I thought I would have something different and also something that won't cripple me financially if there is a major problem. My Boxster was pretty reliable, I did 0 - about 36,000 miles and didn't experience any major problems. I agree with others, anybody that says the Boxster and especially the S isn't a proper Porsche knows nothing about cars. It's a bit off topic but the Boxster has a much better setup being mid engined and goes back to the roots of Porsche with the 550. I think people came up with this silly idea because of the first 200BHP Boxster that was much cheaper than a 911 and not that powerful. Things really changed when the S model was launched, bearing in mind it shares a lot of components with the 911.
I can't comment on the S2000 but I would say that from a financial point of view the Z4 wins hands down, in terms of fun you will not notice a huge difference between the Boxster and Z4
As a final note, I had the 2008 Boxster S & 2008 Cayman S (both 295BHP) for road testing / reviewing purposes a few months ago. Both for 24 hours and I really drove them if you know what I mean
. They were both brilliant to drive but costed over 70k euros each. My 03 Z4 costed a fraction of that, has approx 60 BHP less and I am not having any less fun with it.
As others have said, test drive all three, list the really important things to you and go with the one that ticks the most boxes. You'll have fun no matter what happens!!! Good luck : )
