Here's pictures of front and back All Weather mats purchased from Tesla Shop last week. They all fit perfectly. Online shop chat reps are vindicated!
Frunk and trunk mats coming tomorrow. Will post further updates at that time.
The only nit would be that the rear mat 'tabs' at the top are a tad smaller than the carpets that the car comes with. Still has more than adequate coverage IMO and largely depends on how far back or forward you pull the front seats. Not sure if Tesla will update these for refresh spec since they like to keep it simple, so may just continue selling the single size for a while yet.
Overall, pretty happy I don't have to return these!
