Out of a Peugeot 206 CC, my criterias were simple : no roof, rear wheel drive, 2/4 seater, at least the same performance as the 206, useable on a day-to-day basis, and preferably good looking.
My list was : Z4, S2000, MX-5 (NB or NC...), Boxster (old one, 986 like), Toy MR, MG-TF, 350Z.
Cars like Elise or Speedster were discarded due to the lack of practicality (does this word really exist ?

).
So....
Toy MR : don't like the look of the car.
Boxster : don't really like the look of the 986, and in my budget, i could only afford a 10 years old car with 100.000++ km on the board.
350Z : too expensive. But i'm considering it now.
MG-TF : i really like the car, but some details are just "no way", like the non-adjustable steering wheel or the non-reliable engine...
MX-5 NC : was brand new at the time, so buying one meant loosing a bunch of money.
MX-5 NB : it was a close call. Very very close. Cheaper than the Z4, less powerfull but i think the fun and driving pleasure would have been in the same order of magnitude. And would have been a good introduction to a future Z4...

S2000 : now, here i have a problem. I love the car, love the engine, love the way it handles, juste fondamentally love the gearbox.... but already 3 friends of mine ahev one. Don't want to be the 4th in line... and depending on how you look at the car, it's sometimes gorgeous, and sometimes just ugly.
And then, i came upon an ad for a 2003 Z4 with only 25.000 km on the counter, just in my budget... and for 2 and a half year now, it's been the best choice i ever made (concerning cars at least

).
