You could take the Premire now, and put in or keep your RST order and trade, or choose not to, when the RST arrives. News is the semiconductor issues are not going to abate for at least 6-12 months. Your Premiere will hold its value, so this may not hurt you much. Just don’t put a lot of extra $$ in it beyond stock until your RST of choice arrives…because you won’t get that $$ back.
Also, I’d expect to see +1 on interest rates by fall, if financing is a consideration. And, at least in the Yukons, the base price is up $600 since the beginning of the model year, and you are watching what the inflation rate is right now..
