My Chrysler PT Cruiser Convertible, which I love, is over 140K miles. Never had to do much work on it (no engine work), but have been looking for a second car, just in case. I fell in love with a 2014 500 POP for sale w/ 40K miles because of its look & retro green color & standard trans. It's just me in household, so should I buy? What miles age should I expect to last? I need my PT to drive on the beach, and the 500 for work. All I have found on user sites read 100K +. Doesn't seem very long these days. Thanks for any longevity guidelines.
