Trade-In vs Private Sale vs Auction: Which Gets You the Most?

When it's time to sell a piece of equipment, you've got three main options. Each has tradeoffs between price, speed, and hassle. Here's an honest breakdown.

Option 1: Dealer Trade-In

What you get: Typically 60-75% of fair market value.

Pros:

• Fastest option: trade it in the same day you pick up the new machine
• Zero selling hassle: no listings, no tire kickers, no negotiations
• Tax advantages: in most states, you only pay sales tax on the difference between the new machine and the trade-in value

Cons:

• Lowest price: dealers need margin to recondition and resell
• Limited negotiating power: take it or leave it

Best for: When you're buying a new/used machine from the same dealer and want a clean, fast transaction. The tax savings can offset some of the lower price.

Option 2: Private Party Sale

What you get: Typically 85-100% of fair market value.

Pros:

• Highest price potential: no middleman markup
• You control the process: set your price, choose your buyer
• Can be selective about who gets the machine

Cons:

• Takes time: average 2-8 weeks to find a buyer
• Hassle: listings, photos, phone calls, showings, negotiations
• Risk: scams, bad checks, liability during showings
• No tax advantage: buyer pays full sales tax

Best for: When you have time and want maximum return. Works well for popular models (Cat 320, Bobcat S650) where buyer demand is strong.

Option 3: Auction

What you get: Typically 70-90% of fair market value (highly variable).

Pros:

• Definite sale date: the machine sells on auction day, period
• Competitive bidding can drive prices up on desirable machines
• Exposure to a large buyer pool (especially the big national online auctions)

Cons:

• Unpredictable: prices swing wildly based on who shows up and what else is for sale that day
• Fees: auction houses typically take 5-12% commission
• No reserve risk: if you run a no-reserve auction, you might sell for less than expected
• Transportation: you usually need to deliver the machine to the auction site

Best for: When you need a guaranteed sale date, have multiple machines to sell, or the machine is too specialized for easy private sale.

The Bottom Line

Method	Typical Return	Speed	Effort
Trade-In	60-75% FMV	Same day	None
Private Sale	85-100% FMV	2-8 weeks	High
Auction	70-90% FMV	2-4 weeks	Medium

The right choice depends on your priorities. If you don't know your machine's fair market value, start there. Everything else follows from having an accurate number.
