This 1988 Mercedes-Benz 560SEC was registered in California through the current owner’s purchase in 2022. A subsequent multi-year build by Aspard Garage of Los Angeles, California, included the installation of a 5.4-liter M113 V8, seven-speed automatic transmission, limited-slip differential, instrument cluster, automatic climate controls, and engine management, braking, and suspension components that were sourced from a 2009 SLK55 AMG. The body was modified with flared metal fenders and AMG-style bumpers and side skirts, and additional details include European-specification headlights, a fabricated exhaust system, 18″ three-piece AMG-style wheels, power-adjustable front seats, an adjustable steering column, central locking, and a touchscreen Alpine head unit with Apple CarPlay connectivity. This black-over-black C126 560SEC is now offered by the seller on behalf of the owner with a build sheet, a clean Carfax report, and a clean California title in the owner’s name.

The body was modified with metal flared fenders that are said to have been fabricated by CMS Motorsports before the car was repainted in black. Further details include European-specification headlights, AMG-style bumper covers and side skirts, gloss-black trim and badging, fog lights, a power sunroof, a power antenna, and quad exhaust finishers. Photos of the car during the build are viewable in the gallery below.

Custom-fabricated 18″ AMG-style three-piece wheels are mounted with staggered-width Continental ExtremeContact Sport 02 tires that were recently installed. The front and rear subframes were transferred from the donor SLK55 AMG along with the suspension and brake components. The donor car’s ABS/ESP module was also fitted, and silver AMG-branded calipers are featured up front.

The power-adjustable front seats were sourced from a later model and were trimmed in black leather with microsuede inserts before they were installed. Matching upholstery extends to the dashboard, door panels, and rear seats. Further appointments include gloss-black interior trim, R171-specification climate controls, seat position memory settings, central locking, and a touchscreen Alpine head unit with Apple CarPlay connectivity. The reupholstered trunk is equipped with a concealed storage compartment below the floor.

The four-spoke AMG steering wheel is mounted on an adjustable column, and it fronts a retrofitted cluster that is said to have been sourced from the donor car that supplied the driveline. Instrumentation includes a 200-mph speedometer, an 8k-rpm tachometer, a clock, a fuel level gauge, and a digital display. The digital odometer shows 37k miles, approximately 1k of which were added under current ownership.

The 5.4-liter M113 V8 was sourced from a 2009 SLK55 AMG with approximately 35k miles, according to the seller. A replacement wiring harness was installed during the build along with custom engine bay covers. Photos of the engine bay with the covers removed are presented in the gallery below.

The car was retrofitted with a seven-speed 7G-Tronic automatic transmission, a custom driveshaft, and an AMG-specification limited-slip differential during the build. A fabricated exhaust system with AMG mufflers and MagnaFlow catalytic converters has been installed.

The build sheet from Aspard Garage lists the modifications performed.

The Carfax report is free of accidents or other reported damage.

The car has not been inspected by the California Bureau of Automotive Repair or Air Resources Board following the engine swap, though the BAR inspection process has been initiated. The car cannot be sold to an in-state private party buyer.
