Have no problems using high mileage cars for traveling, PROVIDED, that I know the car like the back of my hand. I know what and when maintenance was done ( ex: belts, brakes, fluids, tune ups, tires, suspension, electrical, etc.). To pick a car out of the blue would be insane..Example: my sister's car with 150k on it, and I have no clue what the maintenance schedule was on it. Triple AAA card is a MUST have.
