The Garage is the page that the site redirects to upon login. When logged in, users are able to view their currently selected car or title, rearrange their car collection, collect mystery boxes, buy cash, start a regular race, or start a friend race. The Customizer is also accessed through the garage, which allows users to equip or paint their currently owned cars, or equip stickers, titles, and trails. The design of the garage page will also change depending on if the user has a Gold Membership.
Garages consist of sections with thirty spaces for a user's cars. A user with more than thirty cars will end up having multiple garage sections. After filling the entire garage, a new 30-spaced section will appear.
Having more than one garage section and selling cars to the point of owning less than 30 cars will not result in the excessive sections disappearing; they stay at the bottom of the garage regardless of conditions. The maximum possible amount of garage sections without using any exploits is seven.
Prior to March 29, 2014, players were unable to rearrange the cars in their garage. Instead, cars showed up alphabetically ordered in small boxes. This changed after an update in which the garage was reformatted. 
On June 5, 2019, as part of the site-wide redesign of Nitro Type v3, a new garage look was released. It included the new colors used by Nitro Type, as well as larger buttons and the ability to paint cars in the garage rather than the Dealership. The mystery box's opening animation was also changed, as well as the design. The features of the heading itself were also changed, where the name and title are displayed, top 3 badge, and other commodities (cash, nitros, XP).
On February 10, 2020, an update was made that allows players to click on the gold logo that appears on Gold Members' profiles to make fireworks that explode into gold confetti appear. Next, any user's selected car can be clicked ten times to make an explosion of tiny versions of that car appear. Lastly, clicking on the cash icon next to one's cash will result in several bundles of cash exploding out of it. All three things can be done on public profiles or in one's personal garage.
Prior to the update where levels reset every season and racers leveled up by their number of races, racers leveled up by exp points, which depended on speed, accuracy, and number of races. The first level required 600 XP to level up, and each level after that required more exp than its previous one.
On October 16, 2020, an update was added which gave The Xcelsior V12 a "shimmering" effect when it was applied in the garage. There was an update for some new features and actually included a bug in which applying the All Terrain Vehicle in the garage would make it appear much larger than it really is. This may have been due to the fact that the ATV's size was increased on the enhanced track.
On February 6, 2021, the ability to sell cars was removed.
On March 13, 2021, the Customizer was added to the garage through the Customize Cars & Loot button. The Customizer replaces some of the functionality of the garage, so features like selecting and painting cars were removed and must be done through the Customizer instead.
On April 16, 2021, the ability to customize trails was added. Because of this, the trail equipped by a user shows up in the section of the garage displaying the currently equipped car. The ability to hover the cursor over the display to move the car around was also added. However, cars with no trail equipped cannot be moved around by the cursor.
On April 17, 2021, the direction that cars and trails face in your garage was changed and the space around your selected car was changed from white to grey.
On June 11, 2021, the $ symbol was changed to $0.
