Shopping for a 2020 Mustang in 2025? You’re going to see some wild price swings. Base EcoBoost models are going for around $15,800, GT Premiums sit near $28,000, and Shelby GT500s? Still commanding close to $60,000. We pulled real market data to see how these stack up against buying new.
- 2020 EcoBoost Mustangs have dropped 38% to around $15,800, making them cheaper than many compact SUVs
- GT Premium models hold value better at 22% depreciation, now selling for $28,000-$30,000
- Shelby GT500s lost only $14,000 from their $74,000 sticker, trading at $59,500-$92,000 depending on miles and options
The EcoBoost Reality Check
A clean 2020 EcoBoost with average miles? You’re looking at about $15,859. Trade-in value sits around $13,504. That’s a 38% drop from the original $26,000-$27,000 sticker.
Meanwhile, a brand new 2025 EcoBoost starts at $33,515. Go with the five-year-old model and you pocket roughly $17,500 in savings. The catch? You’re getting 315 horsepower either way. Same 2.3-liter turbo four, same 10-speed automatic. The newer car gets wireless CarPlay and a bigger touchscreen, but mechanically, they’re twins.
GT Models Tell a Different Story
Want the V8 growl? The math changes. A 2020 GT Premium in clean condition trades for about $28,116. That’s only 22% depreciation over five years, which is mild for a performance car.
A new 2025 GT Premium costs $52,675. You’re paying nearly $25,000 extra for the new car smell and three years of warranty coverage. Both have the same 5.0-liter Coyote V8 pumping out 480 horsepower.
Walk into any used mustang dealer lot right now and you’ll find 2020 GT Premiums listed between $30,000 and $35,000. Clean titles, under 40,000 miles, all the options. Most are well-kept machines that somebody traded in for the next thing.
GT models hold value better because buyers actually want them. EcoBoost models? Fleet purchases and rental cars. GT Premiums went to enthusiasts who loaded them up and took care of them. Lower supply, higher demand, stronger resale.
The Shelby GT500 Anomaly
A 2020 Shelby GT500 stickered at $74,095 originally. Today? Listings range from $59,499 to over $90,000. Some have barely depreciated. Low-mileage examples with the Carbon Fiber Track Pack are selling for $82,000-$105,000.
Why? Ford made 760 supercharged horsepower feel like an event. The GT500 became a modern muscle car icon with limited production and massive power. It was also the last of the S550 generation GT500s before Ford moved on to the S650 platform.
What This Means for Your Wallet
Budget-conscious and want the Mustang experience? A 2020 EcoBoost at $15,800 works. You’re getting a good-looking sports car for Honda Civic money. Gas mileage is decent, insurance won’t kill you, and it’s quick enough for fun.
Want the V8? A 2020 GT Premium, around $28,000-$30,000, gives you 95% of what the new one does for $22,000 less. You lose some warranty and the latest tech, but you gain equity.
Shopping for a GT500? Values are holding because these cars are collectible now. Find one under $70,000 with reasonable miles and somebody either priced it wrong or needs cash fast.
The Market Right Now
The nationwide average for a 2020 Mustang across all trims sits at $28,489. That pulls data from EcoBoost economy models up through six-figure Shelbys.
Interest rates matter here. Financing a $28,000 used GT at current rates might cost you the same monthly payment as a $48,000 new one at a promotional rate. Run the numbers both ways.
Your Best Move
The sweet spot right now is a 2020 GT Premium. You get the full V8 experience, reasonable depreciation behind you, and a car that still feels current. EcoBoost works if you want cheap thrills. GT500? Only if you’re collecting or you need that supercharger whine.
A five-year-old Mustang is still young in car years. These run 200,000 miles if you maintain them. The S550 platform is proven, and parts are everywhere. Check local listings, test drive a few, and see what feels right. The $20,000-$30,000 range is where the real deals live.
