I drove BMW for two decades, and switched to Audi in 2014 because the BMW design was getting sketchy. Still in the same 2013 S4 - it’s been a joy to drive, and at 253k miles has been the most reliable vehicle I’ve owned.

I recommend top tier detergent gasoline, but don’t shop exclusively Shell

You mean the e60 still is a shockingly ugly, generic design and the e39 looks like a classic. (I fixed it for you.)
