⚙️ Performance & Powertrain

This 1965 Buick Riviera underwent a comprehensive, show-quality restomod completed in 2019, transforming it into a modern performance grand tourer while maintaining its timeless mid-century design. Under the hood lies a supercharged 6.2-liter LS3 V8, managed by Holley Terminator X engine controls and paired with a 4L70E four-speed automatic transmission and a 3.23:1 rear axle.

The build includes a custom stainless-steel exhaust system with 2.5″ headers and Stainless Works mufflers, along with a Walbro fuel pump, Billet Specialties water pump, and MSD ignition components. The valve covers are finished in gray Cerakote, while an Optima battery sits beneath a custom enclosure for a clean presentation.

🛞 Chassis & Suspension

The Riviera rides on a fully upgraded chassis featuring RideTech air suspension, providing adjustable ride height and a comfortable, composed driving experience. A front sway bar and adjustable rear Panhard bar sharpen handling, while power-assisted four-wheel disc brakes with drilled and slotted rotors ensure confident stopping power.

The car sits on staggered Schott Cover-Loc “Accelerator” billet wheels—18″ in front and 20″ at the rear—finished in titanium with polished accents and wrapped in Nitto NT555 G2 performance tires (245/40 front, 305/35 rear).

🖤 Exterior

The Riviera’s body was smoothed and refinished in deep black, with the front cowl filled and the antenna, emblems, rocker trim, and lower grille trim deleted for a cleaner, modernized look. The vertical grille elements were refinished in black, further accentuating the car’s aggressive, monochromatic aesthetic. The result is a sleek, minimalist silhouette that honors the original design while adding contemporary flair.

💎 Interior

Inside, the cabin showcases Southern Vine Green Relicate Napali leather throughout, expertly crafted by Cato’s Custom Upholstery in Tucker, Georgia. Both front and rear power-adjustable bucket seats were rebuilt with new cushions, and the dashboard and door panels were trimmed to match.

Additional highlights include:

• Dark Charcoal Finetuft velour carpeting

• Walnut-rimmed Gran Sport steering wheel, refinished in black

• Custom Classic Instruments gauges (140-mph speedometer, oil, coolant, amperage, and fuel)

• Aftermarket climate control with discreet console-mounted knob

• Kicker Bluetooth-capable stereo system

The odometer currently shows 1,600 miles, reflecting the limited use since the build was completed.

🎒 Trunk & Accessories

The trunk compartment is fully upholstered in matching green leather and includes a four-piece custom luggage set by Laurent Nay of Broût-Vernet, France, inspired by the Mercedes-Benz 300SL, adding a bespoke finishing touch.

📜 Additional Information

• Build receipts included

• Twin Bentley-branded umbrellas

• Clean Texas title in the seller’s name
