How much is a first-generation Mustang worth?

The first-gen Mustang market is huge and well-documented, which keeps pricing predictable by body style and engine. Here is the rough 2026 picture for solid cars.

Pricing tiers (driver to excellent, estimated)

• Six-cylinder or base 289 coupe: $20,000 to $40,000
• 289 / 302 fastback or GT: $45,000 to $90,000
• Mach 1 (1969-1970): $50,000 to $100,000
• 428 Cobra Jet cars: $90,000 to $180,000
• Boss 302: $120,000 to $200,000
• Boss 429 and Shelby GT500: $200,000 to $500,000+

What moves the price

Body style first, since fastbacks command far more than coupes, then engine code, then originality and documentation. A Marti Report, numbers-matching drivetrain, and original sheet metal all add real value. Convertibles sit between coupes and fastbacks.
