Our first kid just arrived recently and with the heat-wave(yeah I know 90deg in WA is heatwave) I was looking into getting shades for the rear pano roof. Unfortunately Tesla wants $150 for them! Anyone have a recommendation for alternatives? Also does anyone have a side-window shade they like that works well? I've seen a few that roll up with the window but I don't know how we'll they'd work with the weather strips.
