Purchase advice: Cadillac SRX or any other SUV?!

Greetings Motortalker, some know that I’m almost 10 years old and have a Cadillac Seville STS 99er. Now I’m looking for new talent in the house, after which I noticed that the stroller bought the wa already does not fit in the Seville. I want to look around for a SUV. I would like to have a Escalade (I drove a month, a dream!). However, this is a bit exaggerated. Now I got the SRX, big but not too big. The same as in Seville. Technically probably a lot similar?! But are there any diseases? What should I pay attention to when buying/watching? Is the SRX at certain places susceptible? V6 is already really cheap, or should I rather take the V8? Are there different equipment variants? Look forward to ideas suggestions and information! Thank you =)
