For me, no. The difference that makes the Cadillac experience so bad is the order process and poor communication that follows. The whole allocation process is the stupidest thing I have ever heard of in modern commerce. And all of the incorrect, misleading, dishonest, confusing and straight up bullshit information that surrounds the allocation, ordering, and delivery process is infuriating. And IT DOESN'T HAVE TO BE THIS WAY. GM's allocation process is nothing more than a gift to dealers and a FUCK YOU to customers.
Case in point: I ordered a Tesla Model 3 within a few months of ordering my Blackwing. To order the Tesla, you go to their website, choose what options you want, and give a $250 non-refundable deposit on your credit card. The website gives you a 3-month window of when to expect delivery. In my case, I ordered in May and got a delivery window of Sept. - Nov. Then you download the Tesla app and as you get closer to your delivery date, the window narrows, eventually dropping to 6 weeks, then 4 weeks, then 2 weeks, then you get your VIN, and the car is shipped, and finally you get notified that it is at the dealership. All from the app in your phone. You don't need to call anyone, join a forum, decipher event codes, plead with a salesperson, talk to Keri, hear about constraints, pray to the goat gods, etc. Nothing. Just order the car, get a time estimate, and wait for it to arrive.
In total, it took almost exactly the same amount of time for the Blackwing and Tesla to be delivered. The difference was, any time I wanted an update on my Tesla order, I pulled out my phone and loaded the app. Sometimes the dates would shift around, but it was always their best estimate of when my car would arrive, and ended up being pretty accurate. Our car was delivered in September. Tesla is dealing with the same supply chain and labor issues as every other car company, but somehow they have figured out how craft an actually acceptable customer experience.
