I'm Joe. Licensed dealer, 30+ years, 50,000+ cars.
I come to your driveway with a firm offer before your dealer visit. If it makes sense to sell to me, you walk in with cash. If not, you trade in knowing you checked. Zero risk.
Thinking about trading in? Here's what you should know:
Most people know trade-ins pay less. But most people don't know how much less. Here's what the numbers actually look like:
| Private Sale | CurbSold (Joe) | CarMax | Dealer Trade-In | |
|---|---|---|---|---|
| What you get | Highest price | CarMax price or better | 14-18% below private | Lowest offer |
| Time investment | 10-30 hours over 2-4 weeks | 20 min at your door | 1-2 hours at their store | 5 min at the dealer |
| Strangers at your home? | Yes, multiple | No. Just Joe. | No | No |
| The offer changes? | Buyers negotiate endlessly | No. Firm offer, period. | Rarely | Often changes at signing |
| Paperwork | You handle everything | Joe handles everything | They handle it | Dealer handles it |
| Payment | Cash from stranger | Same-day check | Check in 2-3 days | Applied to new car |
| Example: 2021 Honda CR-V | ~$24,000 | $20,600+ | ~$20,600 | ~$18,500 |
That last row is the one that matters. I guarantee to match or beat any CarMax offer, so CarMax is my floor. On a typical 3-5 year old SUV, the gap between the dealer's trade-in offer and the CarMax price is $2,000-$3,000. One real example from a personal finance forum: a car that traded in for $1,200 and got a $4,000 offer from CarMax. Same car. Very different numbers.
It's not personal. It's math.
The dealer's goal is to sell you a new car. Your trade-in is a side transaction. They'll offer you the lowest number you'll accept because their real profit is on the new car, the financing, and the add-ons. Industry data shows dealers make up to 4x more profit per trade-in than per new car sale.
Here's what happens behind the scenes: the dealer checks wholesale auction values (the same data I use), then subtracts reconditioning costs, a profit margin, and a buffer for risk. The number they show you is typically the wholesale floor, not the retail ceiling.
That's not a scam. It's how the business works. But it means you're subsidizing your new car purchase with money you could have kept.
I come to your home, wherever you are in the San Fernando Valley or Ventura County. I inspect your car, scan the VIN, take a few photos, and run it through a professional valuation tool that uses real-time auction and market data. While you watch.
Then I give you a number. A firm number. Not a range, not a “pending verification,” not a “we'll call you back.” The price I quote is the price I pay.
If my number makes sense for you, sell to me. I write you a check on the spot. You walk into the dealership the next day with cash for your down payment instead of handing over your car for less than it's worth.
If my number doesn't make sense? Trade in as planned. You've spent 20 minutes and learned exactly what your car is worth on the open market. That knowledge alone is worth the call.
Tell me what you're driving and when you're heading to the dealer. I'll schedule a 20-minute appointment at your home before your dealership visit.
I look at your car, run the numbers using professional valuation tools, and show you the firm offer. No surprises, no adjustments later.
If my offer makes sense, I write you a check and take the car. If not, you trade in with confidence knowing you got the best available number. Either way, you win.
“The price I quote is the price you get.”
I buy cars for a living. I've done this for 30+ years. And I've told people to take the trade-in when the numbers made sense. I'll do it again.
The California trade-in tax credit is real. When you trade in at a dealer in California, sales tax is calculated on the net price after subtracting your trade-in value. At ~8.5% in the San Fernando Valley, a $10,000 trade-in saves you about $850 in tax. A $20,000 trade-in saves $1,700. That's real money, and it narrows the gap.
If I buy your car separately, you pay full sales tax on the new car. I'll help you do the math so you can see which path nets you more.

I'm Joe. I started helping friends and family who'd call me after seeing the dealer's trade-in number. They'd be in shock. I'd pull up the real market data and show them what their car was actually worth. Then I'd buy it from them. They'd walk into the dealership with cash instead.
I did this enough times that it turned into a business. That's why I started CurbSold. I guarantee to match or beat any CarMax offer. If I can't beat the trade-in, I'll tell you that too. I'd rather earn your trust than your car.
