The worst car I've ever owned was a 72 Fiat Spyder. That car was built in retaliation for WW2! The brakes worked ok, thats the best I can say for it. I've never owned a bad Plymouth and I've had a few. I once had a 69 Pontiac Firebird, no brakes, paint peeling off it, front end headaches from day one! I bought it new and the dealer wouldn't fix a thing till I got the area rep on his case! My 2002 pontiac is almost as bad, Rack and pinion, brakes,master cyl, fuel pump, repaired intake twice! It seems the 3.4 motor has a intake from a 1942 John Deere and they don't really match up too well so they leak like a sieve.I know why they collapsed! I had a 1980 pinto and loved it, in 70,000 miles I replaced the timing belt and a rear wheel bearing. My son totaled it! My wife had a 88 Beretta that really ran but ate alternators. The computer finally quit in it and I replaced it with a junkyard piece...no more alternator problems. My wifes 84 Ford LTD wagon had a 3.8 V-6, what a POS! The first motor wiped a cam at 24,100 miles! I bought a junkyard low mileage motor and swapped it out. That lasted about 18 months and started making strange noises. We gave it to our son..LOL He eventually traded it for a set of mags.
