The Flutter is only on the manuals and is a result of a common and known issue with many types of roots blowers from numerous different OEM platforms. I certainly wasn't expecting it to be any different when I bought my ZL1 and I was pleasantly suprised. I suggest you try the ATI Damper with 5% OD Pulley and see if it doesn't go away.
44-60k is a lot of miles for a car of this performance level. $500-1,000 for strut replacement is pretty reasonable considering the tech involved.
Why do people think the ZL1 requires a special tech cert. to change the oil? I can see doing major work, but this thing is still an LS motor. Doesn't get much simpler than that.
These are not really cons, but rather scrapping the barrel for things to talk about. IMO
