I would suggest filing a complaint with the Better Business Bureau whether you have an attorney or not.
http://www.bbb.org/us/Consumer-Complaints/
I went through the BBB to file complaints against Wells Fargo for bad business practices and Chevrolet regarding my '01 Corvette's unresolved fuel pump issue. The complaints were quickly responded to by both companies; something that didn't happen when I went at them alone. Wells Fargo resolved the problem within a week of the complaint. Chevy fixed the fuel pump issue by sending me to another dealership, extended my warranty to 100k miles with $0 deductible, and refunded me money for various costs.
My wife is a corporate attorney. This doesn't make me an expert, but I have seen some patterns with respect to the realities of litigation. Depending on how reasonable or stubborn the other party is, the winner is usually the one with the deeper pocket. Unless your attorney is paid on contingency, the dealership knows you're only going to go as far as you can reasonable justify the cost.
The BBB is free.
Good luck.
