Chevy Tahoe As First Car?

My Uncle says he will give me his 2012 Tahoe, I will have to pay for the insurance and gas though. Is it a good choice? I have experience, I have been driving my Grandma's 2008 Honda Pilot for nearly 2 years and I sorta like big cars since I am high above everyone. Except a lot of my friends keep telling me "Chevy is Unreliable" "Its Too Big You can't handle it" etc, I can also possibly get a Volvo XC60 from my Grandfather, but I have heard that it requires more maintenance than Nikki Minaj's ***, and it is very expensive to do that maintenance. What do you suggest? Volvo XC60 or Tahoe? Which is a better choice, I have a lot of money saved up so if you have any other choices under 20k I would be happy to hear so. I care more about luxury than speed.
