I got my 2002 V6 Mustang
3.8L from my aunt. She was the original owner, and took such good care of it. She took it to the ford dealership at least once a year to get a full check up and everything. She was never late, and was usually early on all of the maintenance and all of that. All of the mechanics that have worked on it were amazed at how well taken care of it was. I mean this thing was never even parked in the drive way, always in the garage.
I want to keep this car in great condition, and want it last a long time. It now has 100,600 miles on it, and I've had to replace some things on it once it hit 100,000 miles. The serpentine belt, tensionor (spell check), some idler pulleys, break light switch connector, coil pack, and some other small things (spark plugs, spark wires, etc). Lol, as soon as it hit 100,000 miles, all of that went bad within a couple of days.
So what are some things that I can do (cheap things, $30 or less) that will keep the car running smoothly and prolong its life?
