Car dilemma a nice one at that! Your thoughts...

[Sparkynw]

After many years of many cars then a spell without while I got my business going I've got back to being able to get myself something to enjoy both driving and polishing! I'm 40 soon so maybe a bit of midlife crisis going on but heres my short list..
05 Boxster S
05 SLK 350
Z4 coupe
05 350Z
S2000
All have their own merits, it will be used only for fun, running costs not really an issue as miles will be low...
My last 2 cars were e46 m3cab and a 540M sport before that....
All experiences with any much appreciated....
