Dreamed of owning one of these for a long time. Finally traded my Jeep Wrangler for this certified used Z4. What an incredible automobile. Handles like a dream and I'm stared at and asked about it 24/7. Handling, fuel economy, and styling is like no other.
Comfort and handling.
Perhaps better cup holders and BMW should give lifetime access to automatic phone dialing emergency system instead of 1 year but these are certainly minor.
