Lexus IS Convertible or Infiniti G37 convertible?

if you had a option of buying one of these two cars in the upcoming year, the Lexus IS convertible or Infiniti G37 convertible, which on would you buy and why?|||I would select the G37, and being a Lexus fan that hurts, but the G37 is brand new while the the IS250 is already showing it's long tooth. To make a convertible from the 350 engine would have made more sense, but Lexus chose to use the 2.5 liter instead. The IS250 is about two three years too late into the cycle to be a consideration. If Lexus comes with a convertible for the next generation IS and puts the 3.5 liter in, then we'll talk again.|||It's hard to imagine the IS ragtop, because i've never seen a 2-door IS. The G37 is easy to imagine , It would be a Z-car with the rough edges polished off -- James Bond tothe Nissan's Mike Hammer.|||Lexus will make in 2009 the IS250 and IS350 in a convertible. If you would like to see it go to Lexus.com and look under future vehicles.|||i dont think the lexus is is available in convertable.
