I think that some remanufactured CIC are showing up in the ETKA which are considerably cheaper than new, though. I estimate some $2000 in the retrofit - with some extra discounts in parts, hardware installation done DIY, assuming that there is already an iDrive installed in the car- could be possible by the end of the year, and some $1200 can be get back from selling the old iDrive parts on ebay, so the effective cost should be less than $1000 if done right.
Add perhaps some $500 if there is no iDrive already installed in the car.
I think anything downwards of 3000$ is relatively worth it.
At least for me...
Because as you mentioned the leap between the old Idrive and the New one is night and day!
