Unveiled only a few months back (August 2017), the new M5 is arguably the most aggressive and technologically advance midsize sedan BMW has built to date. But this doesn’t mean it can’t be improved. And BMW used the 2017 SEMA Show in Las Vegas to showcase a range of M Performance parts that enhance the M5 inside and out, as well as under the skin. It may seem a bit ridiculous to showcase performance- and visual-enhancing parts only a couple of months into an already awesome sedan’s life, but this is how the market works nowadays. While some will be more than happy to take a stock M5 home, others will pay for a few extras and a slightly customized appearance.
