Sell My Car MO vs. Dealer Trade-In.
The strongest argument for trading in — the sales-tax credit — isn't exclusive to trading in. Missouri gives you the same credit when you sell to us and buy your next car within 180 days. That changes everything below.

The honest rundown
How a trade-in actually works
Trade-ins are one-stop convenient: the dealership appraises your car, applies an allowance against the one you're buying, handles the title, and in Missouri, the trade value comes off the taxable price of your purchase. On a $20,000 purchase with a $10,000 trade, you pay state and local sales tax on $10,000 — real money, and the reason "but the tax credit" ends most trade-in debates.
Here's what ends the debate the other way: Missouri law (RSMo 144.025) extends that same credit to an outright sale. Sell your car to anyone — including us — and buy a replacement within 180 days, and the sale proceeds offset the taxable price of the purchase. Which leaves the trade-in allowance standing on its own merits: a wholesale number negotiated inside a larger deal, where it's the easiest place for a discount on the new car to quietly become an underpayment on your old one.

The comparison, in plain rows
Fair is fair
Where a trade-in honestly wins
If you're buying from that dealership this week anyway and they put a genuinely strong allowance on paper — it happens, especially when they need your model for their used lot — one appointment settles everything, and that convenience has real value. Late-model, high-demand trades sometimes pull aggressive allowances a standalone buyer won't match that day.
Our advice isn't "never trade in." It's: get the allowance in writing as its own number, separate from the new-car price. If it beats both of our offers cleanly, trade with confidence — and if it doesn't, you've lost nothing but a signature.
Our side of the ledger
Where we win
- Missouri's 180-day rule means selling to us keeps the sales-tax credit — the trade-in's headline advantage, neutralized by state law.
- Our two numbers stand alone: nothing to bundle, nothing to bury.
- Profit sharing pays you from the retail sale — the spread a dealership keeps on every trade.
- A written, physically reviewed trade allowance above our cash offer triggers the $300 guarantee.
The honest verdict
Trade-ins won on tax math for decades — but Missouri's 180-day rule hands that same math to sellers who take the check instead. Once the tax credit travels with you, the only question left is whose number is bigger, on paper, by itself. We like our odds two-to-one.

Dealer Trade-In vs. us: quick answers
No. Under RSMo 144.025, if you sell your vehicle and purchase a replacement within 180 days, the sale proceeds offset the taxable price of the new purchase — the same credit a trade-in gets. Keep your bill of sale; your license office applies the credit at titling.
