Amazing experience so far! Have had my Tanzanite Blue/Verganza 530i X-Drive a little over a week. Been driving Lexuses since 2003. Wow, what a difference. Steep learning curve but well worth it. Just ordered a set of Michelin Pilot Sport A4 all seasons to replace the crap Contintental GXs that came on the car. First BMW Jim, Champaign, IL
