I'm curious about something. Does anyone know approximately at what VIN number they changed the springs? I recently took delivery (3 weeks ago) of a "new" April build model 3, however, it is VIN 15,11x, which is really low from what I understand. Every thing seems ok with the car - none of the usual issues. However, the ride seems perhaps a little stiff to me, so I was wondering if that is something I should bring up with tesla service before my 30 days are up.
