I’d like to hear from any Model 3 owners who have replaced their driver & passenger side windows with the double-panel glass in a pre-2020 Model 3. I’d like to know what the cost was and what the sound experience was. Is the improvement immediately noticable? Worth the cost? My M3P is from Sept 2018 (s/n ~60,000), so it was not an early production unit that generated the first noise complaints (they made some soundproofing improvements early on). The noise is not bad but at highway speeds I’d like to see some improvement.
