The brakes are bad. no auto parts store sell rear brake drums in my area not even the dealer. leaks oil. the gas tank leaks so I can't fill it above the 1/4 mark. all the things wrong now are because I can't get parts.
Handles very poorly.
I recommend searching Google or some other search engine for parts. Just type in something like "1987-1990 mercury tracer" and you might find something.
Someone from a Mercury Ford dealership told me you might find parts that supply the old Mazda 323. The 1987-1989 Tracers have the same engines as the 323 but there were more 323s in production. The old Tracers were Mazdas in disguise! 70% Mazda, 30% Ford (mostly trim).
