Nice thing about an American car vs Foreign is that the American cars are relatively inexpensive to fix. Foreign makes are, almost by rule, expensive to fix.
I used this fact to my advantage to drive my 1985 Deville to 238,000 miles and my 1993 Deville to 298,000 miles. The cost of the stuff I had to fix (some I did myself, others I took to a reputable garage) was reasonable and very affordable. Had I owned foreign makes, it would have been much, much more expensive.
In 1996, I bought a 1980 Mercedes 300SD (diesel) for my Dad. Man, that sucker was expensive to maintain. When little things broke, you paid through the nose to get them fixed. In the end (in 2001), the engine couldn't keep its compression and I convinced my dad to just get rid of it or it was going to continue to be a money pit.
