They are two different products doing two different jobs. A lot frame is a consumable that gets swapped constantly and needs to be cheap. A delivery frame rides on a customer's car for years and needs to survive that. Buying one SKU for both means overpaying on the lot or under-delivering at handover.
Should a dealership use the same plate frame on lot cars and sold cars?
No, in most cases. The lot frame's job is to make inventory look consistent for weeks or months while being cheap enough to lose. The delivery frame's job is to carry your name on a customer's vehicle for years. Those requirements pull in opposite directions on cost and durability.
Running one SKU is simpler on paper and usually more expensive in practice. Either you put metal frames on lot cars and lose them to turnover, or you hand a customer a thin plastic frame at delivery and watch it come off in the driveway.
How do lot-use and delivery-use frames compare?
Different service life, different failure mode, different budget. The table below is the spec sheet for each job.
| Requirement | Lot / inventory frame | Delivered vehicle frame |
|---|---|---|
| Service life needed | Weeks to months | Years |
| Times installed and removed | Many | Once |
| Audience | Shoppers on your lot, listing photos | Everyone on the road, for the life of the car |
| Material | Plastic is usually right | Metal is usually right |
| Finish priority | Consistency across inventory | Matches the vehicle's trim |
| Cost sensitivity | High — it is a consumable | Lower — judged as advertising, not parts |
| Quantity driver | Inventory count plus attrition | Monthly deliveries |
| Acceptable loss rate | Meaningful | Near zero |
What does a lot frame actually need to do?
Look consistent, mount fast, tolerate repeated removal, and cost little. It sits on a car that has no permanent plate, gets photographed for listings, and moves to another unit when the first one sells. Nothing about that job rewards an expensive frame.
Consistency is the real value. A row of inventory wearing identical frames photographs better and reads as an organized operation. A row wearing four different frames from three suppliers reads as a lot that does not sweat details, and shoppers notice.
Plastic suits this well. It is cheap, it is light to ship between rooftops, and it will never bleed rust down a bumper the way a cheap plated steel frame can after one salt-belt winter.
What does a delivery frame need to do?
Survive weather for years, look like an accessory rather than an advertisement, and be good enough that the customer does not want to remove it. That last requirement is the whole game, and it is the one thin frames fail.
The timescale is longer than most dealers plan for. S&P Global Mobility put the average age of US light vehicles at 12.8 years in 2025, with passenger cars averaging 14.5 years. Your frame does not need to last that long, but every year it does is free advertising you already paid for.
Match the finish to the vehicle. A black powder-coat frame on a blacked-out truck looks factory; a bright chrome frame on the same truck looks aftermarket. Getting that right raises retention more than any design change to the artwork.
Should the two frames carry different artwork?
Usually the same name, sometimes different information. The lot frame can carry your name and city, since the viewer is already standing on your lot. The delivery frame is the one that needs to work for a stranger who has never heard of you.
Some stores run a separate identity for pre-owned inventory, in which case two designs make sense on the lot as well. If you do that, keep the typography consistent so the two read as one business.
Do not use the lot frame to test artwork you intend to use at delivery. Lot frames are seen at ten feet standing still; delivery frames are seen at fifty feet moving. A design can pass the first test and fail the second badly.
How many of each should you order?
Size lot frames off inventory count plus attrition, and delivery frames off monthly deliveries. Those are different numbers driven by different things, and estimating one from the other is where dealerships end up with too many of the wrong frame.
| Step | Lot frames | Delivery frames |
|---|---|---|
| Base quantity | Units on the lot needing a frame | Average monthly deliveries over 12 months |
| Multiplier | Frames per vehicle displayed | Frames per delivered vehicle (one or two) |
| Attrition | Add for breakage, loss and cars sold with the frame still on | Minimal |
| Buffer | Enough to cover a seasonal inventory build | Roughly a month, to cover a 2–3 week lead time |
| Reorder trigger | Count quarterly | Tied to delivery volume |
Delivery frames are the better candidate for a recurring subscription, because the consumption rate tracks a number you already watch every month. Lot frames are the better candidate for a bulk order, because the quantity is stable and the unit price matters more.
Does the customer keep the delivery frame?
Some do, some do not, and the ratio is largely in your control. Frames come off when they read as advertising a customer did not agree to. They stay on when they read as a finished accessory that suits the car.
Three things move that outcome: material quality, finish match, and restraint in the artwork. Name on top, one contact detail on the bottom, a finish that matches the vehicle's trim. Adding a tagline and a phone number and a URL is what turns an accessory back into a billboard.
Be honest that some customers will remove it regardless, and that is fine. The frame still traveled with the car through the first weeks of ownership, which is when the vehicle is most visible to the buyer's own network.
What about service loaners and demo units?
Treat them as a third category, sitting much closer to the delivery frame than the lot frame. A loaner is driven on public roads by someone who is not yet a customer, often for days at a time. That is exactly the exposure a delivery frame is built for.
Demo units follow the same logic. They are driven by staff, parked around town, and they represent the store the way a sold vehicle does. A thin, faded frame on a demo quietly undercuts the impression the rest of the vehicle is making.
The rule that works on the ground: any vehicle that regularly leaves the lot gets the delivery frame, sold or not. Anything sitting in a row waiting to be photographed gets the lot frame. That line is far easier for a porter to apply consistently than one based on ownership.
Should you run one SKU or two?
Two, unless your volume is small enough that splitting the order pushes both into a worse price tier. In that case run one metal SKU, use it at delivery, and use unbranded holders on the lot until volume justifies a second design.
The two-SKU approach usually costs less overall despite looking more complicated, because you stop losing good frames to inventory turnover and stop handing consumables to customers.
Frontline Frames manufactures both sides of that split in the USA — plastic and metal, in standard chrome, black powder-coat, polished chrome and antique pewter — with a 2–3 week lead time, one-off bulk orders or recurring subscriptions on a monthly through semiannual schedule. Price both quantities at your real volumes in the builder, or see how it works.
