Merge safety

Create a Car Merge Guide

Test Create a Car merge updates safely by using duplicate parts, keeping a backup car, and avoiding rare-part losses.

Use duplicates first

The safest merge test starts with parts you can replace without hurting your main build.

Keep a backup car

Never run merge tests on the only car that funds your cash flow.

One experiment at a time

Change one variable so you can tell what affected the result.

Separate rumor from result

Treat YouTube, Discord, and code pages as leads until your server confirms the behavior.

Respect source conflicts

MERGER and NEWMERGER appear in current code sources, but both should be tested before budgeting around them.

Safe planning rule

Create a Car can change after updates, so treat visible server numbers as your source of truth. Use this guide as a decision framework, then verify codes, costs, and rewards in-game.

FAQ

When should I merge parts?

Merge only after you have duplicates or a protected backup setup.

Is MERGER active?

Some sources list MERGER active, while SuperCheats marks it expired. Test in-game and treat it as needs-check.

How do I avoid bad merge losses?

Use replaceable parts, keep notes, and never risk the core part of your income car.
