PSA: Lego Bowser's Muscle Car Is Retiring - Save Big On 3 Mario Sets Before They're Gone

Bowser's Muscle Car is a 458-piece build that is technically considered an expansion playset, but it doubles as an awesome and very affordable display set. If you love the King of the Koopalings, this set includes a buildable figure that can stand on its own or sit in the driver's seat of his signature ride from Super Mario 3D World.

The unique purple and yellow car is 6 inches long, 4 inches wide, and 2.5 inches tall. It comes with a pair of bomb accessories to lob at your Interactive Lego Mario figures from the starter sets. If Mario, Luigi, or Peach manage to steal Bowser's car, the Action Tag in the driver's seat creates unique audio and visual reactions. But keep in mind, those interactive elements are only possible if you own one of the electronic starter set figures.

The looming retirement of Bowser's Muscle Car could be related to the upcoming Mario Kart Lego set featuring Bowser, which recently leaked and is expected to launch on August 1. If you want to build some other characters and karts for Bowser to race in his muscle car, here's a list of the currently available Lego Mario Kart sets. We've also listed the Interactive Lego Super Starter Courses, in case you need one of the electronic figures.

The Soda Jungle Maker Set offers a bunch of unique components that can be used to add some colorful variety to your Lego Mario courses. This is one of the coolest expansion sets that focuses on a collection of smaller builds rather than one centerpiece item. And with the $20 discount ahead of its discontinuation, you're getting a lot of value here.

The 598-piece set comes a trio of Lego Mario figures, all of whom are part of Bowser's crew: Piranha Plant, Wiggler, and Pink Shy Guy. Along with the figures, you'll piece together various environmental trappings from New Super Mario Bros. U's Soda Jungle world. Notable accessories include a Special Pipe and the Customization Machine, which is paired with two Question Blocks and interacts with the Lego Mario starter set figures. Multiple other Action Tags are scattered throughout, making this a great choice for youngsters who enjoy building and playing Mario levels in Lego form.

If you love Piranha Plants, check out the 540-piece Lego Super Mario Piranha Plant. This is one of a handful of Lego's Nintendo-themed display models for adults, and you can save 20% at Amazon.

Goombas' Playground is the smallest of the three soon-to-be retired Lego Super Mario building sets. This 173-piece build comes with three Goombas, each of which has a different facial expression, along with a seesaw and hollow tree trunk with perches. You can snag this $15 kit for only $9.39 while supplies last.

At nearly 2,000 pieces, the Mario Kart display model is one of the largest Super Mario Lego sets. Compared to the smaller-scale Mario Kart playsets for kids that launched in January, the finished build has a lot more detail. This is the most realistic recreation of the mustachioed character's modern design--his head and arms are posable--and the kart looks ripped straight from Mario Kart 8 Deluxe.

The completed model measures in at approximately 12.5 inches long, 7.5 inches wide, and 8.5 inches tall. The set can be displayed flat or at a drifting angle with the included, buildable display stand.

Like other Nintendo display models, Mario & Standard Kart comes with a physical instruction booklet and support for an interactive guide in the Lego Builder app on iOS and Android. With the free app, you can watch each step of the build process in 3D and manipulate the diagram to look at the work-in-progress from any angle you desire.
