For Sale: 1970 Chevrolet Impala in Mesa, Arizona

This 1970 Chevrolet Impala Convertible is a distinctive, SEMA-built restomod that combines classic American styling with extensive modern customization. Built by Jimenez Bros Customs for the prestigious SEMA Show, this Impala showcases an impressive level of detail throughout its interior, exterior, engine compartment, and trunk. From its custom two-tone Cadillac green paint and specially commissioned three-piece wheels to its extensively modified LS-based V8 and bespoke interior by renowned Southern California upholsterer Ron Mangus, this Impala represents a substantial investment in craftsmanship, performance, and individuality.

The exterior makes an immediate impression with its custom green paint inspired by an early-2000s Cadillac CTS color. The two-tone finish features a matte upper section contrasted against a high-gloss lower body, separated by hand-applied pinstriping with subtle copper detailing. The bumpers have been modified and color-matched for a more contemporary appearance, while extensive chrome deletes and painted trim create a cohesive, streamlined design. Oracle headlights and a custom front turn signal delete further distinguish the front end. Completing the exterior are custom 20-inch, three-piece AG Wheels, specifically manufactured for this Impala and its SEMA Show appearance. Every element has been carefully selected to complement the car's distinctive styling, creating a custom convertible with an unmistakable presence.

Inside, the craftsmanship continues with a fully customized interior completed by Ron Mangus Upholstery in Southern California, a respected name associated with numerous award-winning automotive projects. The front and rear seating began as late-model Chevrolet Camaro seats before being extensively reshaped, separated, and upholstered to suit the Impala's custom cabin. Black leather with copper-colored suede inserts complements the exterior's unique color combination, while custom door panels and a bespoke center console contribute to the refined appearance. A Dakota Digital instrument cluster brings contemporary instrumentation to the classic dashboard, accompanied by a Lokar floor shifter, tilt steering column, and Restomod Air air conditioning system. Entertainment comes courtesy of a custom Kicker Audio installation featuring Bluetooth connectivity, amplifiers, and substantial trunk-mounted subwoofers. Additional details, including integrated phone charging connections, demonstrate the attention devoted to making this one-off interior both visually impressive and functional.

Under the hood sits an extensively modified GM LQ9 V8, originally sourced from a Cadillac Escalade. Starting with the 6.0-liter LS-series platform, the engine was reportedly completely rebuilt with a .030-inch overbore, stroker rotating assembly, custom aluminum cylinder heads, and an upgraded performance camshaft. Additional performance equipment includes a FiTech electronic fuel injection system, aftermarket intake, aluminum radiator, and electric cooling fan. According to the consignor, previous dynamometer testing suggested approximately 450 horsepower and 450 lb-ft of torque, although supporting dyno documentation has not yet been located. Power is delivered through a 4L60E four-speed automatic transmission, which the consignor reports was recently rebuilt by Riverside Transmissions, a performance transmission specialist in Southern California.

The custom engineering extends beneath the car with an adjustable air ride suspension system incorporating AccuAir components and VIAIR air compressors, both brands associated with the original SEMA build. The air management system retains its AccuAir tank and e-Level components, with an updated control interface installed following changes in availability of the original equipment. The VIAIR compressors are prominently displayed within the custom-finished trunk, creating an installation that is as much a visual feature as it is a functional component. Braking is handled by four-wheel manual Baer disc brakes featuring drilled and slotted rotors and custom-colored calipers coordinated with the vehicle's overall design. Baer was also among the sponsors involved in this Impala's SEMA project. Throughout the vehicle, numerous additional custom details reflect the effort invested in creating a cohesive show-oriented build.
