I'm surprised the CT6 is on the list. It's too new, the old retirees who normally buy Cadillacs haven't had a chance to even see one yet. But their flagship vehicle might be hurting because of the Tesla Model S - and the PHEV versoin just doesn't compare. Think of it. This way, a base CT6 starts at $54k. For just $20k more you can get a Model S, that same $20k more gets you a CT6 plugin with only 35 miles of range. That makes the Model S a no brainer. Now if the CT6 plugin were discounted by $20K, it could be a very attractive car. I hate to wish poor sales on GM, but that translates into a lower price for me.
Edit: cars.com is already showing CT6 PHEVs at $66k. It's getting closer....
