I have a hellcat redeye, approximately one of your $100k cars. I've thoroughly enjoyed the car in the nearly 2 years I've owned it. But, I'm barely over 6,000 miles, and I've killed 2 batteries and just had the starter replaced and a loose ground (fixed/replaced under warranty). The loose ground may not have been a factory defect: I had to have the wiring harness replaced after some rodents chewed through some of the wiring...
