It seems more drivers are trying to squeeze some extra miles out of their cars and trucks before they re-up. This isn't exactly news -- since the recession hit we've seen this trend grow and grow -- but a recent survey conducted by CarMD.com put some interesting figures out there for us to chew on. They found that "nearly 50% of survey respondents indicated that their current vehicle had over 100,000 miles. A combined 69% reported that they planned to drive their current vehicle for 150,000 or more miles (13%), or until their vehicle dies (56%)." Those are some interesting numbers if you ask me. And with all of these cars driven longer by responsible, maintenance-minded owners, there are a lot more do-it-yourself mechanics popping up. Great!
