I see it's been a while since you posted, but I just wanted to ask — did you end up driving the Dart that night? I was wondering if the brakes and lights held up fine after sitting for so long. Seems like short, cautious drives are okay if you prep a little first, but I'm curious how the car actually did after that long break.
I ran into the same kind of deal a while back and just used bookinglane.com to find a driver. Super easy, they showed up on time and knew exactly what they were doing. It saved me a lot of stress trying to line something up last minute. Definitely beats begging a buddy to stay sober or messing with random Craigslist ads.
