I apologize for intruding on your forum. When I bought my current car a few years ago I found this great site:
http://www.carbuyingtips.com/. When my best friend decided to lease a car a few weeks ago I sent her there and she said the advise they had was very helpful and provided her with a terrific education on the process and especially about GAP Insurance (which the dealership charged an insane amount for but her insurance company only charged about $9/year.
Good luck!
