Junk Mechanics Garage & Upgrades

Which garage and shop upgrades to buy first in Junk Mechanics, so storage, selling space, and repair speed stop throttling your flip loop.

What exists

Garage progression is confirmed

A creator ran a full "I bought EVERY garage" progression, confirming garages are a core Cash sink and capacity lever. Buying the right garage at the right time is a real decision, not a decoration.

The levers

Storage, selling space, tool speed

Capacity lets you hold more flips, selling space moves stock faster, and tool speed shortens repair time. These three replace the volume of the auction-to-dealership loop.

Claim state

Costs are community-reported

Exact garage prices and upgrade costs are community-reported; creator progression videos confirm the purchases but not current in-game numbers, which shift with updates.

Upgrade order

Buy the fix for your actual bottleneck

There is no universal 'best' garage. There is only the upgrade that removes the limit currently throttling your flips.

Storage first

Capacity caps profit per session

If you are leaving flips on the table because you hit the storage limit, a capacity upgrade increases profit per session immediately — the highest-leverage first buy for most routes.

Selling space

Move stock to free the loop

Selling-space limits throttle how fast you turn cars into Cash. More room extends the flip loop before you have to stop and sell.

Tool speed

Faster repairs compound

Fast repairs mean more flips per session. Tool upgrades are worth more the more you grind the auction-to-dealership loop.

Buy order

Avoid buying ahead of need

Creator progression buys garages in order, but each one only "pays for itself" once the previous limit is actually constraining you. Buying ahead ties up Cash you could be flipping with.

Upgrades, gamepasses, and the profit route

Capacity comes from both Cash upgrades and Robux gamepasses. Pick the cheaper fix for the same bottleneck.
