The vehicles are divided into three categories (economy, comfort, premium) based on their model and age. You can view the conditions required for your vehicle by going to Your cars > Relevant car > View listing, then Conditions required by Getaround. You have to check that these conditions are met during the licence check for each driver, and also check that the payment card used is in the name of the main driver and that it matches the rental agreement.
Each car gets moderated after it has been registered. If your vehicle is placed in the comfort or premium category, you will be informed by email.
To find out the category of your vehicle, go to Your cars > Manage your listing > Your conditions.
