Hey guys. I just bought my wife a gently used 2013 Suburban LTZ 2wd. With the wealth of knowledge I've gotten from you guys about my XK, I figured I would take the opportunity to expand my horizons on the wife's new ride. I plan on just maintaining it, telling her she's going to be driving it until the wheels fall off. Anyway, does anyone have any experience with Suburbans or know of any things to look out for? Thanks ahead for any input.
