I've had my '08 Kia Optima LX for nearly 3 years, I bought it new when gas went to $4/gal back in '08.
I got rid of my Hemi Ram and bought the Kia thinking I'd keep it for a little while and trade up later.
It now has 107,000 miles on it and has proven itself an EXTREMELY reliable little car.
I've done nothing to it except change the oil and filter religiously every 5k miles, had one brake job done at 75k miles, replaced the battery at about 60k miles, put on a set of new tires at 72k miles (I put on Kumho KH16's since that's what it came with), and flush/fill the radiator every 45k miles.
I did almost all the maintenance myself. IT'S THE MOST RELIABLE CAR I'VE EVER OWNED and I love it!
