Rev up your love engine! Faster than you could name the hosts for “Dating in the Fast Lane” – which are Between The Lines, Affirmations, General motors and GM PLUS – you could score your Prince(ss) Charming. Folks will gab for 3-5 minutes in the front and backseats of a Cadillac, Saab or Saturn, while a car horn will initiate each new date. After each date, every person will rate their date on a feedback card, and matches will be notified. “We wanted to do something that was a lot more experimental with the vehicles (and) something fun that’ll involved potential customers and that demonstrates we understand the community,” said Travis Parman, GM’s LGBT media relations manager. For $5 (which goes to Affirmations, and will be matched by GM), sign up for a time slot at their Web site, http://www.affirmations.org.
