One was an AWD 19" received September 30 2018. The other is a LR RWD Aero received late November (after Thanksgiving).
First car had left lane change not working correctly. It would continuously blink. Quickly fixed. RWD car had a scratched sill plate (driver's side) and some small paint issue. Tesla quickly corrected.
AWD on a hot day can, for the first mile, exhibits popping sounds as if the window is about to crack. The RWD is just totally solid. It is the trip car because of its greater range. 5754 miles on AWD and 7277 on RWD. Yes, more miles on the newer car. The AWD replaced my 2013 Genesis R-Spec. The RWD replaced Kim's 2013 Mustang.
