I purchased a Model 3 last March. It therefore has the rough (sporty) suspension. I asked about this and was told that Tesla will install a new suspension that is soft. Softer than what is in the new Model 3's. It was described as like riding an old Cadillac. I have never ridden an old Cadillac and they said the only person to have it installed paid to put the original back in at about $7000. So I am wondering if anyone else has had this done and what they think about it. I do not drive a lot on curvy roads, but do drive on Oakland's pothole-ridden streets.
