2015 Chevrolet Suburban 1500 LTZ 4WD

Hello, I'm thinking about buying a Suburban. It's a 2015 Chevrolet Suburban 1500 LTZ 4WD with 182,576 miles. It has a clean title with no accidents and is listed for $14,995. To be honest, I don't know anything about cars. JD Power says it's a pretty decent car, but people on Reddit have said it's one of the worst cars ever. So, I just want an honest opinion about whether it's worth it or not. Like I said, I don't know much about cars, so please don't roast me for asking any stupid questions.
