While it is usually considered a luxury car brand, Buick has produced several exceptional muscle cars over the years. The 1970 Buick GSX was a true-blue muscle car in looks and performance. Drivers could choose from yellow or white bodies, each with its own distinctive stripe package. Kit features a detailed 455 cubic-inch V-8 engine with a cold-induction air cleaner and a hood-mounted tach, a fully detailed suspension with a dual-exhaust system, a separate rear spoiler, soft black tires, chrome-plated parts and decals with authentic stock and colorful GSX graphics.
