I actually had a Model Y on order for awhile. I wanted to go full electric after enjoying an Audi PHEV for 3 years. I wanted another hatchback or an SUV. However, then I started reading the Tesla forums. My goodness. I discovered a lot. First, the Tesla's don't have features which I consider critical to my driving experience and safety: Apple Car Play and Rear Cross Traffic Alert. The Tesla fans said their Nav was good enough, but for me,nothing beats Waze at rush hour. I like Siri letting me know about texts, reading them, and letting me reply. The fan boys said that I should back in to parking spaces. That sounds just great: visit Home Depot with your SUV and try to load the stuff after backing in. Crazy.
Other, less critical features were missing like blind spot warnings in the side mirrors. I always wanted a 360 top view camera system -- not available on the Teslas. Love it on the I-Pace. I like listening to Sirius and FM radio. Tesla offered neither. Build quality horror stories abounded: panel gaps, mismatched or bad paint jobs. On the other hand, Tesla has big focus on self-driving which simply does not appeal to me. I love the auto cruise control, but I've tried the self steering on the I Pace and it's neat, but I don't see the point. That's just my opinion.
Scariest were the service stories. Tesla has had tremendous growth, but their service departments have not grown nearly enough. They are overwhelmed. I also researched this forum and the UK version prior to getting the I Pace. Forums are always filled with problems, but Tesla seemed much scarier to me.
Finally, there is styling. This is 100% subjective -- eye of the beholder and all that. Still, I've never owned what I consider an ugly car. And, the more photos I saw of the Y the more I disliked it. To me it looks bulbous and blah.
Speaking of styling, since my Audi lease was coming up, I went to Audi dealership to look at the etron GT. It looked pretty good -- definitely a luxury vehicle, although I don't know what is up with the Germans and their arms race to build bigger and bigger grills. I'm not a fan. Well, the local Audi dealer is also a Jaguar dealer and I walked 200 feet to their showroom and there was this Indus Silver I Pace and... that was it. Love at first sight and still loving it.
