Counterpoint - it’ll be a lot more work to transfer CE features to the CD. Drop the 617 or a 617 into the CE and enjoy. No one in the US is going to restore that 230CE. It’s rare in the US but not worth the cost of restoring. I expect you’ll regret letting the features get away the next time your ACC or a power window acts up.

Does it have SLS? Is there a pump at the front of the cylinder head?
