Build A Car Empire Keep-or-Sell Sheet

Print this in your head before the next crate. Build A Car Empire is a keep-or-sell game. The official HUD art is a green check and a red X. This sheet is the decision, not the lore. For the full argument, stay on keep or sell. For cash after the sale, use how to get money.

Named banners (official media)

Banner	Rarity	Official odds note	Default call
Kooper	Common	1 in 2	Sell, unless it is your only printer
Aventa	Epic	Unstated beyond Epic chip	Keep
Concept Ghini	Exotic	1 in 920,584,217	Keep, screenshot, never Auto Sell

Those three names come from official lot art, not a datamine. Other bodies exist on the showroom. They do not get a row here until a banner or keep-or-sell card is visible. When a new name appears, screenshot the chip and add it mentally using the rarity rules below. The car tier list is where named rows live long-term.

Rarity rules when the name is new

Read the chip, not the paint.

• Common — fuel. Keep the first if the lot is empty. Sell duplicates. Common is 1 in 2; a museum of Kooper clones is a slow printer with no slot for Aventa.
• Uncommon / Rare / other mid chips — not published on official thumbnails. If a new color appears, keep the first copy, sell obvious duplicates, and do not invent a percentage.
• Epic — keep. Aventa is the public Epic example. A second Epic can stay if it prints more than your weakest Common; otherwise sell the Common, not the Epic.
• Exotic — keep. Concept Ghini is the public Exotic example. Turn Auto Sell off before you even think. Odds on the art are 1 in 920,584,217. You will not “just roll another.”

If the chip is unreadable because the camera is still moving, wait. A mis-tap is permanent. There is no documented undo.

Lot-state modifiers

The default call changes with the asphalt, not with FOMO.

• Empty lot — keep the first Common so something prints. Then sell the next Commons. See getting started.
• Full lot — sell the weakest printer before you keep a mid-chip you do not need. Offline cash needs parked cars, not a jammed row. See offline earnings.
• Broke wallet — sell Common even if you like the paint. The next crate is the upgrade path.
• Auto Sell on — only if the filter cannot touch Epic or Exotic. The pass is 39 Robux. Cheap is not the same as configured. Pass priority.
• Luck pass on — still sell Commons. 5X LUCK! at 679 Robux does not make a Kooper into Concept Ghini. Crates and luck.

Cards and collection

The Roblox description says “discover cards and collect new cars.” There is no public card list as of 12 Sep 2026. If a card is not a parked car, do not spend a lot slot on it. If a card later becomes a keep-or-sell body, treat the chip like any other banner.

Collection is parked printers plus the Exotics you refuse to sell. It is not a completionist sticker book until Trifall publishes a checklist. The tier list is the honest index.

Thirty-second script

1. Crate animation ends.
2. Read rarity chip.
3. Match the table.
4. Tap once.
5. If you kept, park it. If you sold, look at cash and decide whether the next crate is actually affordable.

Do not open Codes mid-board. Do not open this wiki mid-board on mobile if it covers the red X. Glance, decide, tap.

After a patch

A silent universe save can change sell values without a trailer. If Commons suddenly sell for nothing, slow down and read September 2026 plus updates. Do not copy a keep/sell/destroy short from Car Dealership Tycoon. Wrong game, wrong buttons.

When the board is closed, you can go back to HUD controls or the tools hub. While the board is open, this sheet is the only tool that matters.
