Let me preface this by saying I love the new CTS. I think it's a homerun for GM/Cadillac, but since I lease my vehicles, I may not end up w/ one in my driveway as I had hoped. I'm sorry, but $700/month is just too much for this car. At that payment point there are just so many other good options. For instance, you can lease a new Infiniti M35 for $439/month (39 months, 12k miles per year w/ approx. $5k total due at signing) or an M45 for $499/month (same term).
Let's hope that Cadillac offers more competitive lease deals in the coming months. Call me cheap, but I can't see myself paying more than $550/month for a loaded CTS, no matter how much I love it.
On a somewhat related note, I recently test drove a base engine CTS4. For those interested, here is a thread I started on the CTS on another message board, which includes my test drive impressions:
