Having bitten my tounge until now...
To old mate about the M3, its been mentioned 5 times at least that I read.
To the guy saying its like buying a macdonalds salad. It isnt dude, its like going to the most expencive place in town and ordering the salad, its still going to be 'just' a salad, but its going to taste better, get presented to you better, and you wont have to line up in a que for 20mins to get served by some fat 14yo snotty nosed kid.
To the guy that said a porsche is a porsche, 100% correct mate! Only trouble is if your at a party and say 'ooh I have a porsche' then someone else pikes up 'I have one too, new 997 turbo, whats yours?' you have to answer honestly.
Duncan is right tho, kinda... See this guy is looking for a partcular car. So yeah the 350z might be good, but you need to be compairing the convertable version to the porka. Which isnt as good am I not correct?
So to everyone saying what about this this and this. Well the only cars in this market are the boxster, clk, and mayybe the m3 convertable. If it was my money, and I HAD to have one of those 3, I know which was I would be going. And 99% chance the rest of you would to.
