Bought an S 85D on 4/28. Waited two weeks to find out the car finally was shipped to a service center that was going to replace the MCU and 12v as the car was dead at it's current location. Upon arrival at the new service center and after the work was done, car was still dead and concerns expressed about being "$10,000s to fix". Used Vehicle Sales Advisor (UVSA) stayed in touch entire time and called Friday afternoon, apologized for the hassle, called the car officially DOA, and let me switch to another car.
At first I was disappointed a bit as over the past 3 weeks I think I missed out on some pretty good deals (as I continued to watch the used inventory during that time) but honestly can't complain with what I was able to lock down Friday afternoon within an hour of being able to switch cars. Delivery Advisor then emailed me last night twice coordinating details of the delivery; being told 7-10 business to ship but I'm going to lean on them a bit to see if it can be accelerated given this car is only 800 miles away, and is alive...=), and given my DOA experience. Hoping I can get it by the holiday weekend.
Moral of my story to date: Longer timeline than I had hoped but great customer service so overall still positive and look forward to being an official member of the community!
