My two cents. Since you have an older s maybe ask service the cost to retrofit h jump seats. We’ve had them on both our S’s. My daughter is 11 and is still within the parameters of the seats. Daily she sits in the main cabin. However they’re there when you need them.
Tesla will no longer retrofit h jump seats. I then asked if they would just do the holders/hooks and reinforcement (and I could drop in the seats myself), but no luck.
Also FYI no jump seats CPO available now.
