1969 Ford Mustang Mach 1 428 Cobra Jet 4-speed with Marti Report, listed well under CJ sale prices

Why we picked it

Why we picked it: The VIN on this San Jose-built 1969 Mach 1 carries the Q code, which means it left the factory with a 428 Cobra Jet. It has a 4-speed and, according to the seller, a 9-inch rear with 3.73 gears. It is yellow with a black hood and black interior, the odometer shows 23,485 (actual mileage unknown), and the dealer says a Marti Report comes with it.

Cobra Jet 4-speed Mach 1s have sold for $71,500 to $132,000 this year, and 351-powered 1969 Mach 1s have been bringing close to $80,000. At $64,000, this one is priced well below that. The dealer listing says almost nothing about condition, restoration history or whether the engine is the original block. Treat the low price as a reason to check everything carefully, not as proof of a bargain.

The value check

The seller is asking $64,000. Comparable cars in the same condition have sold for $71,500–$113,000, so the middle of the market is about $92,250. That put this car 31% under.

1969-70 Mach 1s with the 428 Cobra Jet and a manual gearbox sold for $71,500 to $132,000 in March-September 2026 (BaT, Mecum, GAA). Even 351-powered 1969 Mach 1s brought $77,000 to $80,000. A conservative midpoint of about $92,000 puts $64,000 roughly 30% under.

What to check

• Read the Marti Report and match it to the VIN, door tag and options. Check that the block date code and partial VIN stamp (if present) fit a 428 CJ in a San Jose car.
• The listing does not say whether the engine is numbers-matching or give any restoration history, rust or title details. Ask for all of it in writing.
• Look for rust in the cowl, floors and torque boxes, around the rear window, in the trunk drop-offs and on the lower quarters behind the wheels.
• The CJ shock towers and front frame rails take a beating from big-block weight and launches. Look for cracks and old repairs.
• Gateway Classic Cars sells on consignment, so plan a third-party inspection before buying.
