The Chrysler PT Cruiser (PT standing for "Personal Transport") is a retro styled compact automobile launched by Chrysler as a 5-door hatchback in early 2000 (for the 2001 model year) and as a 2-door convertible in early 2005 (added to the 2005 model lineup).Originally conceived as a Plymouth model, the PT Cruiser received the Chrysler nameplate on introduction in anticipation of the 2001 discontinuation of the Plymouth brand.
