Welcome to the Forum Reactivator, Don't worry about the low prices. That's just normal market reactions to a sports car in the winter, and one that's been discontinued by a maker that was just sold to a new owner. Oh, and having a Chrysler nameplate doesn't help.
I've driven my car for over 30k miles, with no "underwater rocks" or other hidden problems at all. I wouldn't hesitate to buy another one.
You will get plenty of information and support here on this forum.
Good Luck with your future purchase.
