I'm in a similar situation with my SR+... love everything else about the car, but the noise and ride quality are barely acceptable... reduced the tire pressure to 35, so it's somewhat better now. This really depends on tarmac quality and average speed, so not really noticeable in traffic or on smoother roads. Also, cranking up the stereo helps, to a degree. I considered selling it, but I just cannot think of an affordable alternative - I love the acceleration and autopilot. Will probably wait until I can test drive a Model Y to see if it's any better.
