* Visual Inspection:
* Badges/Emblems: The easiest way. Look for a "Turbo" badge on the car, likely on the trunk lid or fenders. The absence of a badge doesn't *guarantee* it's not turbo, as badges can be lost or removed, but its presence is a strong indicator.
* Intercooler: A large, often black, box in front of the radiator is the intercooler. This is a key component of a turbo system.
* Exhaust System: Turbocharged models often have a larger diameter exhaust pipe.
* Engine Bay: Look for the turbocharger itself. It's a large snail-shaped component usually located near the engine's exhaust manifold. However, this requires some familiarity with engine components.
* Vehicle Identification Number (VIN): The VIN contains information about the car's specifications, including the engine type. You can use the VIN to look up the car's specifications on sites specializing in vehicle history reports (like Carfax or AutoCheck), or through a Mitsubishi dealer.
* Documentation: If you have the original owner's manual or any service records, those documents should specify whether the car is turbocharged or not.
Important Note: A visual inspection alone isn't conclusive. Someone could have swapped engine parts. The VIN lookup or documentation are the most reliable ways to be certain.
