Although the cars are anything but in the same class, I wonder how any of you convertible lovers would choose between the three. I'm considering getting a '98 pre-owned slk-230 for about the same cost as a new IS300, or partially used S2000 for about the same price. No traction control on the S2000 is a fear since I live in the midwest. I've also heard rumors that the SLK has no cruise control. That seems a bit rediculous. Certainly the most practical car would be the IS3, but there's something about the SLK's hard-top transformation and the blinding (albeit---HIGH-revving) speed of the S2000 that lures me to impracticality. Any thoughts??
