What could be this "Adding rear door glass option for Model Y" ?
- Could this be "tinted" or "not-tinteid" glass ?
- or "laminated" or "not-liminated" ?
- ... ?
Could this be something to make the "RWD" decontended and even cheaper?
Could this be something dealing with the special 2-seat Model Y in France, whitch has a special commercial tax discount?
