I am taking my 99 Malibu on a 13 hour trip one way at the beginning of May. I am slightly concerned because it has 245,000 miles and Im scared something will fail. It runs fine around on shorter trips (6 hours or less). The car has been maintained religiously since it was new, and is still in a mechanically sound shape. In what ways can a long trip like this affect a car? I will only be stopping for bathroom breaks, gas, and food. I do have AAA membership just in case, but Id like to make sure its okay before I go. Its never broke down on me before, but this will also be the longest trip Ive taken in this car that I havent stopped at a hotel. Thanks in advance!
