I didn't see any threads on the Bernina Grey, so I figured I'd open one for the people that are on the fence with this color. The amber effect does give it a fairly brown/amber undertone in certain lighting situations...
I'm coming out of a Bluestone 5 series. The bluestone is more cool blue/grey. Bernina is more brown.
The M550i is a beast. As expected, gas mileage is fairly low in the city with spirited driving, but I'm impressed with highway mpg. I'm getting about 26 mpg, which is not bad for a car with so much power. The suspension is by far the most compliant I've had, even though I had the DHP on other models. Mine came with the Pirelli P7 All Seasons, as I really don't take advantage of the "performance" set, and I prefer having a square setup which can be rotated. They also tend to last about 20k miles, which is way better than what I was able to get out of the staggered sets in the past.
Interior is the same as prior 5s I've had except this has the ID7, which I was used to from my wife's X5. Overall a nice upgrade, but there's nothing really earth shattering.
I've coded NGHB and LVD and a bunch of other settings already. Seems the active driving pro is slightly better than the prior gen.
I threw some 303 Graphene on there too. Pretty easy to apply. Doesn't really make the car very slick to the touch but it looks good and it'll protect it for a few months at least.
Also installed my Max 360c and Blackvue cameras in there. Very happy with the result as it looks very clean. The 360c is wired to the mirror with a mirror tap and it's on a Blendmount mirror mount. The Blackvue cameras you can't see since it's hidden behind the mirror. SunPass transponder was painted black and it's on the right side of the windshield, once again out of my view.
Tints are 5% all around. 3M Ceramic. Clarity is very good. They have a slight brownish undertone as well, so incidentally they do match the paint in certain lighting conditions. I think they match the car very well, especially with the black rims and shadowline package.
The matte ash wood is also nice. I'm surprised that a lot more dealers don't order it on their cars. When I was making the decision to order I couldn't find one that had it so I could take a look at. It does have a hint of blue, but it's awesome at not being reflective and not picking up fingerprints. I also got the Alcantara headliner and really like it.
I also installed the floating center caps (OEM).
Overall, very happy with the way everything turned out. I probably should have gone with the ceramic controls, maybe in the next one...
