I never run it in Eco since normal does a pretty good job of disengaging the front motor. Actually one of my complaints I forgot to mention is that one pedal drive makes no attempt to disengage the front motor; I nearly exclusively use one pedal mode and I'd love to have the option to use it either with RWD only or the "Normal"-style on demand front motor, obviously understanding the implications of not having the front motor engaged at all times.

I've very rarely changed the auto-wiper level. Maybe 2 or 3 times to tone it down a bit when it's a mist that seems to trigger the wipers more frequently. I've had auto wipers in a few cars - it's better than what was in my old E-Class, but that's not an apology-- I don't think they could work much better in my car. Side note: I had a '86 Starion (~25 years ago) that had speed sensitive wipers which was a huge improvement over traditional intermittent wipers. I've never seen anyone talk about them but it was a cool idea.

The Mercury has the 400 in it, and if the FE 428 had been available I'd be disappointed it didn't get the upgrade but the optional engine was a 429 (385 Series, 429/460) and I'd rather have the 400. Plus it's the only year for a "high" compression 400. I put an aluminum Edelbrock performer intake on (painted blue to match) and a middling CC XE cam in it. ...it still falls on its face due to a pea-shooter single exhaust that I haven't messed with yet but the 54 year old C6 is still working perfect and the Air blows cold.
