On top of the 2018 Mustang facelift being leaked, BMW unveiled their refresh to the 4-series line. The changes are typical BMW LCI subtle. Juuuuuust enough to keep it fresh to live out the rest of it’s life cycle without dramatically changing the looks.
I think BMW does facelifts right. I don’t understand the need to heavily alter fascias on a car in the name of keeping it fresh. A lot of the time the new fascias clash with usually unmodified bodywork imo. Some light alterations to the lights, new wheel designs, and some light interior work and you’re golden.
