Vulnerabilities PT-Cruiser??

Hello, comrades! I’m only here as a guest from the Subaru corner, and have a question. The Gulf of my wife is due soon, and the PT would be first choice for her. Financially only the first ones (2000-2002) come into question. Do you have to pay more attention to km or to the year of construction? Is the purchase recommended at all? Where is the best for them? Friendly and with six stars (four for the Advent wreath and two for bad times, so look at us!) Tom
