i have to say forst off, i own my 3rd buick. never owned a ford, so i can not comment on them, but on US auto's i have owned a monte carlo, then 3 buicks. i'll break them down:
forgot the monte carlo. first car, 1980 with a 267 V8. beat the $#%^ out of it, and basically killed it myself. it was smashed, broken into, you name it.
1985 buick skyhawk. was my mothers car, got it for HS graduation. it had 39,000 miles on it in 1991. that's 6,000/ year. she only drove it to and from work, until i got my liscense. i'd say i was responsible for at least 9k or those miles. @ 27,000 before i got it, it needed a cam shaft replacement, basically because it never drove more than 3 miles a day. not GM's fault, the engine never got warm enough for the oil to work properly. i drove that car into the ground, 4 accidents, 1 of them "totaling" the car, and finally sold it to a buddy for $400 with 198,000 miles on it. only real problems were an engine mount that stress cracked (by my hard driving probably), a heater core, and damage from my accidents.
1984 buick regal. got this bueaty with 112,000 miles on it, classic GM V6 engine, car was in great shape. never had a major problem with it, never in an accident. one day with about 180,000 miles on it the timing chain went. the car died, and i was set on buying a "new" car. got it fixed for $650 and sold it for $1100.
1995 buick skyhawk. i still own it. 180,000 miles, V6 and i have had almost no problems again. the heater core went once a few years ago, and a coil went bad. i didn't get regular trans. maintenence and had to have it flushed, and the electric window rack froze and broke 2 times (in -10 or lower temps), but thats about it. just a few weeks ago my driver seat just broke something underneath it, but this car has almost 200,000 miles and it 11 years old. with my fat bellybutton on it all that time, i think it has done good.
now to imports. i worked at a honda dealership for quite a while, and though it was a while ago i can tell you, they are WAY more "well built" than any toyota ever has been. honda's are rock solid. they do have a better feel inside than most american cars. it's the little things, like the vent louvers being solid and not breaking, and things like that.
it is too bad buick does not have a car for someone like me anymore (mid 30's, not rich, single guy) because i'd get another buick in a second.
