455-Powered 1970 Pontiac GTO Convertible Judge Tribute

Description

Pontiac’s 1970 GTO was a muscle car icon, and the rare Judge variant took performance and style to the next level. While original Judge convertibles are prized collector pieces, tribute builds allow enthusiasts to enjoy the look and feel of the legendary package with modern enhancements and personal touches.

This 1970 Pontiac GTO Judge tribute is one such example. A real GTO convertible (not a LeMans), it’s been transformed into a Judge clone finished in eye-catching Orbit Orange with a frame-off restoration completed earlier this year. The chassis was treated with POR-15 for long-term protection, and the build includes a mildly built 455, 4-wheel disc brakes, Boyd Coddington wheels, and a host of comfort and performance upgrades. The seller notes the dash was replaced during restoration, so the mileage shown is not original.

With a clean Illinois title and located in Machesney Park, Illinois, this Judge tribute is ready to cruise, show, or serve as a rowdy weekend warrior.

Ownership History

The current Illinois-based owner has reportedly maintained the car with care and attention while driving it sparingly. With a growing collection and limited time behind the wheel, this Orbit Orange Judge tribute is ready for a new home and more time on the open road. The seller notes, "We just had it painted earlier this year right before final assembly. The car has never really been driven other than for testing after assembly."
