Grow a Car

Grow a Car is a simulation and idle tycoon on Roblox by 0 Thought Games where players purchase vehicles from the Car Shop, place them on a personal plot, and earn passive Cash that accumulates even while offline. Released in May 2025, it has surpassed 25.8 million visits, 53.7K favorites, and a 93.1% approval rating in under a year. Servers cap at 5 players, keeping the experience intimate and low-friction.

The core loop is built around a five-tier dealership ladder - Military, Galaxy, McKaren, Skyscraper, and Wavey - each unlocked by a small gamepass (25-75 Robux). The progression works like this:

• 🚗 Purchase vehicles from the Car Shop and place them on your plot to generate passive Cash
• 💰 Reinvest accumulated Cash into rarer cars that produce higher income per second
• 💎 Unlock premium dealership tiers - Military, Galaxy, McKaren, Skyscraper, and Wavey - for access to rarer vehicles
• 🏆 Build the highest-value car collection on the server and become the richest player

Cars continue generating Cash offline, so every login rewards you with accumulated earnings to reinvest. The dealership tier structure gives the collection grind a clear upgrade path from budget vehicles to exotic premium ones.

Code rewards include exclusive vehicle skins and car parts not available in any dealership - the Posha Diamond Car from the DIAMONDS code is the standout example. These cosmetic and functional rewards give code redeemers a head start on the collection. Grow a Car shares its developer DNA with Grow a City and other 0 Thought Games idle titles.
