Not sure the logic here, spend all this money a new car and then go cheap on accessories for it when the official product is quite $ cheap and includes software and full warranty and it's installed by Tesla themselves
The logic is to support good 3rd party sellers, on parts that are just as good as the Tesla parts. There are no warranty issues. I didn't want the software.
Support the Aussie business selling and installing Tesla parts. We may need them in the future. Like we needed them for the Model 3 towbar installation.
