I bought a 2000 Hyundai Sonata in Apr 2000.
It proved to be the most trouble free and reliable car I ever owned. The only expense to me over the years were, tires, lubes, wipers, and antifreeze change.
The few other items needing attention were covered by the warranty. This included replacing the water pump. When the dealer did the water pump he replaced the timing belt as well. I paid for the belt.
I was planning on keeping the Sonata for at least one more year and then Came across a used 2008 KIA Optima in new-like condition for a price hard to turn down. So I bought it and the Sonata is gone.
I am happy with the Optima. A couple for minor complaints. The driver's seat is not as comfortable as the one in the Sonata. Like the Sonata the AM side of the radio performs poorly. The FM is good.
The Sonata was a V6 and the Optima a 4cyl. I find the 4cyl completely adequate for my driving and I expect to see the MPG to go up a bit.
The Optima, has keyless entry installed buit it did not come with a fob. I have inquired and it appears that even if I find the correct fob at a reasonable price I must still take it to the dealer to be programmed.
