I am kind of funny about driving a car once it has reached 100K miles or so. I have no problems with routine maintenance, new tires, etc...But once the major repairs kick in, I lose confidence in the vehicle and prefer to just get another.
We have a 2001 Durango with 101K miles, bought brand new, has seen better days and time for it to hit the bricks. We are replacing it next month. DS turns 16 and we are getting him either a Camero, Mustang or Charger. We are all leaning towards the Charger.
DD has a 99 Civic with 111K miles. Her grandparents gave to her two years ago for her 16th birthday. They had owned it since it was brand new. She leaves next month, moving 100 miles away to college. She won't need her car there and will just leave it here at home. It won't really be driven while she is gone. As long as it is still going, we won't replace it until she graduates college, at which point we will get her a new one for her graduation gift.
We also have a 99 Malibu with 99K miles on it. Bought it 2001 with 65K miles on it. We never drive it. In the past six months we have only put $10 worth of gas in it and driven it less than 20 miles. But, once DH trades in the Durango for DS's new car, DH will start driving the Malibu for a while.
Over the past few years we have bought a couple of "just for fun" cars. In 2003 DH bought me a BMW 535i for Christmas. Loved that car, it was my toy. DH totaled it 6 months after I got it (not DH's fault). In 2004 we bought a Jeep Wrangler, hard top. It was DH's toy. Kept it about a year, had a wreck (again, not our fault), got it fixed and sold it.
BTW - haven't had a car payment in years and even when we buy DS's car next month we won't have one then either.
