2006 Chrysler PT Cruiser Convertible front

If the PT Cruiser proves anything, it's that Chrysler does retro better than Ford. Its 150-HP 2.4-liter 4-cylinder engine is available with two levels of turbocharging: first to 180 horsepower, then 230. Since the Dodge Neon on which it's based just died, the Cruiser's days could be numbered.
