all in one package." Car and Driver described the design as "highly distinctive, appeals to a broad segment of the public, and is characteristically American." The public's reaction to the PT Cruiser was polarized, but inspired a strong following among owners. Overall, car "was a valuable vehicle for many consumers." Updates PT Cruiser models included the Classic edition, Limited edition, Touring edition, Couture edition (2010 only), "Dream Cruiser", "Street Cruiser", "Pacific Coast Highway" edition", and PT Cruiser GT. The non-GT Turbo () edition models (introduced in 2004) were identified by a "2.4L Turbo" badge on the lower right-hand corner of the rear lift-gate.
