I have worked on some Neons before and they always struck me as being reasonably tough. OE bushings and ball joints seem to hold up as well as those of most other manufacturers, and subframes and other suspension components seem to hold up well to minor wrecks. I can't say much about the drivetrain from experience, except that it seems to last well in stock form. Should you break something in the drivetrain of your Neon Jraymer, say, as a result of going a little overboard with nitrous, there were many Neons made and many of them reside in the junkyard these days, resulting in a plethora of cheap parts being available. I say, run the piss out of it till it breaks, fix it, and do it again.
