The Car Garage is the one place in Storage Hunters: Open World where you can reshape how your vehicle looks and behaves cosmetically. Paint, wheels, spoilers, exhausts, trailers, number plates, and horns all run through this service area. Simple color changes are paid for with Diamonds, while physical parts are bought with Cash after you win them at auction.
Quick answer: Find the Car Garage next to the Shipyard, drive in, and select a service. Paint and wheel color changes cost Diamonds; installing a car part is free once you own it, but the part itself must first be won at a Back Alley, Shipyard, or Cargo Ship auction.

Where the Car Garage is and what it does
The Car Garage is a dedicated service area located close to the Shipyard. It handles vehicle customization only, so it is separate from the Trailer Shop, which sells the trailers themselves. Inside, you can repaint sections of your car, change wheel styles and colors, fit spoilers and exhausts, swap full wheel sets, customize an attached trailer, make a custom number plate, and equip different horns.
Two currencies are in play. Diamonds cover paint, wheel color, wheel type, trailer color, number plates, and horns. Cash buys the physical parts you bring in from auctions. The distinction matters because paint changes are always available for a small Diamond fee, while parts require you to first win them elsewhere.

Repainting is the cheapest way to change your ride’s appearance. Each section is priced separately, so a full color overhaul stacks up in small increments. Wheel color and wheel type are handled in the same interface.
| Option | Cost |
|---|---|
| Primary Color | 2 Diamonds |
| Secondary Color | 2 Diamonds |
| Roof Rack Color | 2 Diamonds |
| Change Wheel Type | 5 Diamonds per type |
| Wheel Color | 2 Diamonds |

How car parts work
Installing a car part costs nothing. The catch is that you must own the part before the garage will fit it. Parts do not appear on a shop menu here; they come out of auctions held at the Back Alley, the Shipyard, and the Cargo Ship. Once a spoiler, exhaust, or wheel set is in your possession, bring it to the Car Garage and attach it with no extra fee.
The Cash prices listed below are the amounts you pay to obtain each part through the auction system. Cheaper parts are entry-level cosmetics, while the high-end pieces run into six figures.

Trailer, number plate, and horn options
You can also fine-tune a trailer at the Car Garage, but you must first buy the trailer from the Trailer Shop. Attaching it is free; repainting it costs Diamonds per section. Personalized plates and horn sounds round out the Diamond-based options.
| Option | Cost |
|---|---|
| Attach Trailer | Free (buy the trailer from the Trailer Shop first) |
| Trailer Primary Color | 4 Diamonds |
| Trailer Secondary Color | 4 Diamonds |
| Custom Number Plate | 5 Diamonds |
| Custom Horn | 5 Diamonds per type |
Installing a part you won at auction
If a part you expect is not selectable, it usually means you have not actually won it at auction yet. The garage only lists parts already in your possession, so returning to a Back Alley, Shipyard, or Cargo Ship auction to secure the item is the fix.
With the pricing laid out, the smart approach is to spend Diamonds on quick paint and wheel color tweaks early, then chase specific spoilers, exhausts, and wheel sets at auction as your Cash reserves grow. Since installation is always free, the only real cost of a full custom build is winning the parts themselves.
