Junk it, sell it yourself or trade it in at a dealer?

Every old car eventually forces this choice. The right answer depends less on the car’s value than on three things: whether it runs safely, how much time you have, and whether you’re buying another car from a dealer anyway.

The three routes side by side

	Junk it (sell to a junk car buyer)	Sell it privately	Trade it in at a dealer
Condition it suits	Doesn’t run, wrecked, flooded, rusted out, failed engine or transmission	Runs, drives and is safe to test-drive	Anything, but value drops fast for non-runners
Your time	One call and one pickup	Photos, listings, calls, showings, test drives	Folded into buying your next car
Who moves the car	The buyer tows it	The buyer drives it away	You drive it to the dealer, or arrange a tow
Paperwork	Title (or other ownership document), two IDs, Seller’s Report of Sale	Title signed to the buyer, odometer disclosure where required, Seller’s Report of Sale	Title to the dealer, who handles the rest of the transfer
Tax effect for you	None	None for the seller; the buyer pays the private party vehicle use tax	A like-kind trade-in comes off the taxable price of the car you buy
Main risk	A low offer if you don’t compare	Payment fraud, no-shows, a buyer who never retitles	A trade-in figure buried inside the new car’s price
When you’re paid	At pickup	When the buyer pays	As a credit on the purchase

When selling privately is worth it

A private buyer pays for a car they can drive. If yours starts every time, has no warning lights and would pass a mechanic’s look, listing it is likely to bring more than a junk car offer. Budget the time, though: you’ll answer messages, meet strangers and handle the test drive.

Protect yourself on the paperwork. Illinois requires the seller to assign the title to the buyer at delivery, and after that the buyer has 20 days to retitle the car (625 ILCS 5/3-112). File a Seller’s Report of Sale with the Secretary of State as soon as the car leaves, so a buyer who never retitles can’t leave you holding tickets. Keep your plates; they’re yours, not the car’s.

When trading in makes sense

If you’re buying from a dealer, the trade-in can save you a trip and a sale. In Illinois it can also cut the tax on the new purchase. The state’s definition of the taxable “selling price” leaves out the value of a like-kind trade-in (35 ILCS 120/1). A $10,000 limit on that credit applied only in 2020 and 2021, and the current text has no cap. That tax effect is the one real advantage a trade-in has over a straight sale, so ask the dealer to show the trade-in figure separately from the price of the car you’re buying.

A private sale works differently. The buyer, not you, files Form RUT-50 and pays the private party vehicle use tax when titling the car, within 30 days of buying it, and the form allows no trade-in credit (Illinois Department of Revenue). That’s one reason private buyers bargain hard on an old car.

A dealer doesn’t want a car that won’t run. They’ll price it as something to send to auction or scrap, and the trade-in number will show it.

When junking it is the right call

Junk it when the car doesn’t run, is badly damaged, has failed an engine or transmission, or would need more in repairs than it’s worth. It’s also the honest choice when the car isn’t safe to sell to someone who plans to drive it.

Junking is also the fastest of the three. We give you a number on the phone, tow the car free from Markham or a nearby suburb, and pay you at pickup in cash, Zelle or Cash App. You still sign over the title and file the Seller’s Report of Sale; what happens after you sell walks through it.

Deciding in four questions

1. Is it safe to drive today? If not, compare a junk car offer with a dealer’s trade-in figure.
2. If it runs, what would a repair cost? Get a written estimate. Our guide to a blown engine or transmission helps with the math.
3. Are you buying from a dealer this month? Ask for the trade-in figure and the tax credit it brings.
4. How soon does it need to be gone? A village notice or a move favors the fastest route.
