I enjoyed my 450+ so much that I regretted not buying a 580. So I traded for a 580 with my dealer. He had one with 1500 miles which a customer had traded for an AMG model. I got it extremely well equipped for $118,000 which is an unbelievable price and I couldn't be happier. First of all, the hyper screen is amazing. Second, coming off three Tesla Model Ss, I found the 450+ very sluggish. The 580 is dramatically quicker, which is extremely useful in heavy traffic.
