You will be disapointed with the turbo 4, no question, regardless of your priority, especially have driven the V TT. Not enough motor for that car.
Further, i have been reading here about everybody being on waiting lists for cars and, after the wait, Cadillac releasing cars to customers without promised trims (programs and chips). It's pretty consistent. I don't know the ins and outs of buying and shipping a car from a distance, but my car is a fun car (hi-po i dont want to put senseless travel miles on) and my tuner/mechanic is in Houston (I reside in DFW.) To ship it each direction, off peak, costs me $300 bucks. direction, give or take.
Leading into...
Try Crest Cadillac in Frisco, TX. (Crest a infinit, Caddlic and Volvo all in a row right there). Not only are they a high volume dealer, they are a high priority dealer. However that works, they get the cars..whole. When i was looking for a new '21 Infiniti RS 400 (over monthly, Covid business 'symptoms' still strong), drive by dealers and online, the only 1 I could find was in Dallas with dealer plates...so used. Drive out to Crest and they had 12 or 13...all new, all available, in every color.
Like wise, im in for maintenance ALOT and always wander through then the caddie dealer. More focused and interested when they started posting up Blackwings...over a two year period, with 3000 mile OIC on my car, i gotta pretty good bead on both lots. When be bought my wife's Caddie, they had every version of the CT-4 (including a nww Blackwing) and CT-5 (no supercharged BlackWing...on that day. I've seen a handful over time.)
To me, it'd be worth an extra $500, 1000 bucks to have one shipped. i guess, do your own math.
Good luck.
