There are numerous variables, but overwhelmingly I've found that if you see any significant rust on the side exterior of these cars, or Panthers (maybe even MORE in the case of Panthers), RUUUUNNN because the undercarriage is 10x worse! Haha.

Lou - I need to post up a pic of the Marquis' undercarriage. It's all covered in some unknown thin black undercoating (not the typical textured rubberized stuff we all know and hate) that seemed to be extremely effective over 65k miles and 25 years in Southern Missouri winters (well, if they drove it in the winter at all). I squat down at random times just to look at it, brings a smile to my face every time :)
