Roblox Realistic Racing Prototype

I’m looking to see a simple yet polished racing prototype built in Roblox Studio. The focus is on a single race-circuit style track rendered with realistic materials and lighting. I need at least one drivable version of each vehicle type—sports car, motorbike, and go-kart—so players can swap between them and test handling differences.

Scope for this first milestone:
• Build one medium-length circuit with clear start/finish, barriers, and checkpoints.
• Configure the three vehicle classes with basic tuning, lap timing, and a minimal GUI leaderboard.
• Keep scripts modular so I can expand content later.

I’ll provide a private place link once we begin; you deliver the .rbxl file plus any custom assets. Efficient, clean Lua scripting and Roblox Studio familiarity are essential, but feel free to leverage existing free models where it speeds things up without hurting quality.

If you can get a playable build in place quickly, we can discuss future upgrades after this prototype is approved.
