Adding infamous models like i3 will consume more time, increasing our data files size, and maybe no one will use it. As we noted from many customers, they always avoid repairing such cars. Besides with the electric powertrain we don't have too much to work with.
When we see there is a demand on such a model, we will add it.
Currently we are preparing to add the G series as it starts to be required.
After we release HW4 we will add more options for on bench, so you will be able to make a key for your car. But this will not be in the next update.
