What i am looking for is how many miles they are engineered for. 150,000, 200,000, or what? The year i am looking at averages in the range of 60-70 thousand miles. What i want to know, is am i planning on purchasing something 20 thousand miles before it plans to die? Went to cars.com already, and while they are helpful, they don't get into life expectancy. Oh yeah, sorry for the bitching about gas prices....but on the other hand, i live in a minimum wage town. Fuel for the mustang ran about 10-15% of my weekly wage. Does that give a better perspective? This is why i want a four cylinder. I don't want to go back to the 60 hour work week.
