Even though the fourth-generation Mustang wasn’t exactly the most critically acclaimed iteration of the American sports car, later models did come with edgier styling and newer 4.6-liter V8 engines.

This 2003 one in particular is interesting because it has been modified by Roush and renamed as the ‘Boyd Coddington California Roadster’. According to its Bring a Trailer ad, this is one of just 13 supercharged convertibles modified by the tuner and the third of four finished in black over Torch Red.

Dual-tone all the way

The entire upper half of the car is black, including the soft-top. Additional exterior mods include the custom bumpers, a Cobra-style hood, convertible styling bar, black-painted 18-inch Roush wheels, Hankook Ventus tires, Brembo brakes and a sizable rear wing – by 2003 standards.

Roush also performed notable chassis modifications, such as adding a front sway bar, specially-valved shocks, lowering springs, rear lower control arms and a pinion snubber.

As for the interior, it comes with red and black leather seats, a factory stereo with a 6-disc CD changer, white electro-luminescent gauges, a Boyd Coddington-signed tachometer and a Roush short-throw shifter.

Then there’s the 4.6-liter V8 engine (with 25,000 miles / 40,000 km on it), which has been equipped with a Roush supercharger, intercooler, specially-designed fuel system, aluminum flywheel and a dual exhaust system with a crossover pipe. When new, this power unit was rated at 379 HP and 380 lb-ft (515 Nm) of torque, with everything going to the rear wheels with the aid of a 5-speed manual transmission.

Back in 2003, this car had an MSRP of $52,537, which included the $22,637 Roush Package.
