Montreal blue was a great color and very similar to my avus blue. Unfortunately, it was’t offered in E39. They stopped after E34 and E36.
OK... allow me to add something too in honor of BMW even I didn't drive high end of them.
...has nothing to do with blue, but by chance I am in Montreal and it makes me smile.
As I mentioned in another thread I drove 2 of them....
Last of mohicans real 328 e90. Was a last year 6 inline 2011 Model. Simply amazing 3 series.
I had Lexus RX-350. After driving this 328 for 30 sec I decided to sell RX-350 with definite decision that this is a real driver's car (ultimate driving machine

).
So, I sold RX and ended up to own this car. From 2012 3 series became F30 stil 328... I hated it... and in 2015 when 48 months ended for 328, signed for a new 328 F30 (was improved from 2012 but still a sh... after 2011). Before final signature for this new one took a last test drive and refused... they made me a super deal for another 36 month of my 4 years young with full warranty.
2018 was last year of F30 it became 330 instead of 328. The problematic engine was changed in this last year F30. It was tested for couple of years on some MINIs and went to redesigned 2019 and up. So I had and enjoyed 330 2l turbo.until last Monday (36 month ended) and took Sonata Sport 19'' wheels, sport seats and pedals

1.6T.
Next business day brought it back to dealership due to not moving fan.
For now enjoying Tucson until the solution will be found. Hope will like Sonata.
Love to hear experiences of others knowing BMW and driving Sonatas.
