This statement applies only to X3. Other models and brands may vary in completeness and accuracy among web sites.
edmunds, kbb, and truecar show all the packages and options appropriate for each model. Cars omits the premium sound package package and has a conflict between the two sport packages and the two cold weather pacakges that does not exist. None show the fees that the dealer pays per car to BMWNA for training and to the regional advertising co-op, together about $500 in NY metro. Although truecar directly, but imprecisely, discusses holdback, this is not relevant because I know of no dealer who would agree to a price so low that it would invade the holdback, which is a rebate that I believe is 2% of MSRP paid quarterly. Also, prices vary among dealers somewhat for accessories, and their installation where necessary, and for document and registration service fees. Prices vary widely among dealers for BMW branded protection plans.
