My little red Honda Civic that I bought new in 2006 just rolled over 200,000 miles last weekend. Not petty for her, but I will be petty and call it my own accomplishment.
I bought it about 4 months before I started hooking up with bey, and the three of us have been through a lot together in the last 12 years.
She's still going strong, too. When we were car shopping, I was kind of sad about trading up, but then we bought that totally impractical classic Camaro instead of anything sensible, so now we are justified to keep a backup car.
