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.
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.
This is my second Bonni and I just love it. I have had only minor problems from it and with good maintenance, it runs great! Right now it has 160,000 miles and still running strong.
