I bought this car at 1 1/2 yrs old. It was a lease car with 43,000. I now have 280,000 miles on this car and still love it. No major problems, I keep oil changes and maintenance done regularly.
Dad drove 130k in 2.5 years w/ no problems. I have had it for 5 years and 50k miles and no problems other than normal maintence.
