1. Visual Inspection: Look for the telltale signs of a GTX, such as:
- A special "GTX" badge on the front fenders and rear decklid
- A functional hood scoop
- Front and rear spoilers
- Deep-set headlights
- A unique blacked-out grille with four round headlights
- Special GTX wheels
2. Engine: The GTX was powered by a variety of engines, but the most common was the 440 cubic inch (7.2 liter) V8 engine. This engine produced 375 horsepower and 480 lb-ft of torque.
3. Transmission: The GTX was available with either a 3-speed automatic transmission or a 4-speed manual transmission.
4. Rear Axle: The GTX came standard with a 3.54:1 rear axle ratio, but optional axle ratios were also available.
5. Documentation: The best way to verify the authenticity of a GTX is to check the car's documentation, such as the VIN number, title, and registration. These documents should match the information on the car's body and engine.
