You haven't really said why you don't like the other cars so it's hard to say. They also all come in actual colours and have carplay so you haven't really given a good reason to consider the Mustang over those hahaCurrently looking at a model Y and cross shopping with a Mustang Mach E.
Not a fan of the BMW i4 , AudiskodaID4 or Merecedes EQA/EQC. I'm also not taken with the idea of the ipace or the polestar. I like the mustang, like it comes in actual colours, like it has craplay, but the telsa is faster and has more fun gimmicks like sentry mode and has everything apart from the pointless full self driving stuff included in the price.
Am I mad for having got my shortlist down to just the Model Y and Mustang ?
What about the Kia EV6/Hyundai Ioniq 5?
If you will do loads of long trips needing en route charging get the Tesla, otherwise just buy whichever you like best.
