"Rolling into the weekend like... 💥," Kourtney captioned the first image of both Penelope (four) and Reign (two), sitting on the Mercedes G-wagon.
The Keeping Up With The Kardashian star took inspiration from brother-in-law Kanye West's song "Last Call" for her captions, using the lyrics: "Mayonnaise-coloured Benz, I push Miracle Whips," for the second pic.
Fans quickly began commenting on the photos, slamming the star for flaunting her wealth on social media.
"Maybe all these pics trying to show off are the reasons you all keep getting robbed," one person wrote, obviously referring to Kim Kardashian's robbery at gun point last year, and Kendall's home burglary last week.
After Kim's robbery at Paris Fashion Week, the reality star was scolded for over-sharing her ~riches~ on Instagram.
