This 1969 Oldsmobile Cutlass Supreme example was crafted by Tomoya Watanabe, a renowned custom builder from Supermachine. Powered by an LS1 V8 engine paired with a 4-speed automatic transmission, it is refinished in Oxblood Red over a reupholstered tan leather interior and features a Burgundy Hertz cloth top, upgraded suspension and brakes, 18” Billet Magnum wheels, power windows, a Vintage Air conditioning system, a custom stereo system, and more. This professionally restored Cutlass Supreme is now being offered for auction by its seller out of California.
The Cutlass Supreme showcases classic muscle car styling, featuring a wide stance, long hood, a short rear deck, chrome bumpers, and a distinctive front grille, split by a vertical center bar and flanked by quad headlights. This example is refinished during its restoration in a two-stage, non-metallic Oxblood Red. It features a Burgundy Hertz cloth top paired with its powder-coated convertible top frame, along with new weather stripping, inner and outer felts for the window channels, and new glass throughout. The front and rear bumpers have been re-chromed and are equipped with integrated parking sensors that are fully functional. It also has 442 badging, dual exhaust outlets, and rides on 18” Billey Magnum wheels wrapped in Michelin Pilot Sport Cup 2 tires. The seller notes a small patch on the top. Detailed images are provided in the gallery.
The interior, fully lined with Dynamat for sound insulation, features seats reupholstered in tan leather, with the driver's seat offering power adjustment. It showcases a leather-wrapped dashboard, an upgraded gauge cluster, and wood accents. Additional features include power windows and locks, Mercedes-sourced carpeting, and a trunk lined with sound-deadening materials. Amenities include a Vintage Air conditioning and heating system, navigation, a backup camera, an alarm system with auto door locks and LoJack, and a custom stereo system with Bluetooth, Apple CarPlay, and upgraded speakers. All gauges and electronics are reported to be in proper working order with no warning lights illuminated.
Power comes from an LS1 V8 engine equipped with a Weiand LS6 intake, headers, and a custom Tommy Hopper exhaust, delivering an estimated 410 HP. The rear wheels receive power through a 4L60E 4-speed automatic transmission with electronic overdrive, rebuilt approximately 3k miles ago. The drivetrain includes a 12-bolt Moser rear end, 31-spline axles, Eaton Posi traction, and an aluminum Be Cool radiator with upgraded dual fans. The suspension has been upgraded with Global West control arms, Hotchkis springs and sway bars, and Bilstein shocks while braking power is facilitated by a Baer big brake kit featuring 13” front and 12” rear two-piston calipers. Recent maintenance includes fluid replacement, an AC system recharge, and a new battery.
This sale will include a window sticker and a clean title.
