..nice little car..any warnings ? one thing I noticed is that in some cars, the cigarette lighter only works if the car is running or key in ignition in start position..this is a problem for me b/c I often charge phone batteries w/ the car off, or even use my laptop on the road, sometimes for an hour or so as I take a break from driving...but don't want to leave the car on or the key in start position..any suggestions out there ?
