How Do I?

Well, at the rate you're making kids, trade them both in on...   and then get a used Ioniq 6 for commuting. 

Ahhh yes! Awesome! 

What I would really like to do is get rid of the SVR and keep the Navi for my wife. Ideally I'd trade in her SVR for a ZDX. Buuuuut, she's stubborn and that's why she has that in the first place. At least she can finally acknowledge she overspent and can't hardly afford her car. That was supposed to be between her and her parents, which is why I was like "whatever" to her buying it (although I had to cosign on it). Long story short, her brother is a POS and her parents have spent a $h! ton of money paying their bills so now it is a my wife and I paying for it. The reason the SVR was supposed to between her and her parents is because she is always helping out at their store but never actually "getting paid" so they were splitting the car payment (the same as when she had her G55). Well now the nearly $1000 car payment is on us and I am none too happy about it. She did know at the time it was more than she wanted to spend but her G55 had gotten to unreliable, and with having a child with her, she simply didn't trust it to get her pretty much anywhere anymore. It had died multiple times driving leaving her stranded on the side of the road. Two times was on the interstate going 70mph and it just died. Luckily there was no kid with her at the time and she could safely get to the shoulder.  Annnnnyyyywwwaaaayyyyy, What would realistically happen is trading in the Navigator. There would be no reason to have a RR Sport, Navigator, and another good size SUV in a ZDX, Prologue, or Lyriq.
