This FM transmitter and auto charger (in one) is something to drool for.
About the only better thing would be a dedicated connection (like the BMW 3 series' option) ... but since I don't plan on buying a new car any time soon (and all of the dedicated options for after-market stereo systems that I've seen are prohibitively expensive), I'll probably get one of these.
I hadn't seen that particular adapter before ... cool.
I like this one:

It lets you use your car's stereo controls to control the iPod...
Yeah, but it doesn't have the charger built in too, so you need an extra wire for those really long drives.
Man, how long do you drive? If you're out for more than 5 hours, take a plane!
That's not an economical option.
Driving to the U.P. takes 6-7 hours.
