2005 Mitsubishi Lancer Evolution RS 4dr Sport Sedan (2.0L 4cyl Turbo 5M)
This car is the most fun vehicle I have ever driven, but I feel it lacks a lot of things for a near $37,000 car. The paint needs to be improved greatly, my front end looks like it's ten years old already.
Definitely the turbocharger and all-wheel drive. The car handles great and you can just about replace everything with improved parts from the aftermarket.
Use more durable paint on the car and wheels. Tune the car so it's not pig rich. Use nicer interior panels, the car rattled with only 10,000 miles on it. Put a stronger clutch in the car.
