your just buying the wrong ones, i have 92,000 miles on my car replaced breaks once and have the stock clutch. nothing has been changed but oil and tires.
as far as american goes my moms pacifica now has about 115 thousand on it and my dads 300c has about 60-70 on it with no problems on either as well as my brothers jeep with 80some thousand. So the american cars are pretty reliable
