18 days, 17 states, fresh 69 Dart Convertible

Sounds like an awesome trip! It goes without saying keep a stash of things in the trunk to get you up and running again in the event issues come up, or some AAA coverage...it is one thing to be stranded on the side of the road, quite another to be stranded with your 11 year old daughter as well.

Safe travels, enjoy making memories that last a lifetime, and for God's sake, with the top down as much as you plan on having it down, wear sunblock!

One gorgeous Dart! The family of your friend will be impressed I am sure.
