In order to get pricing information, go the web site goto build your own...here is the info I got for the three "forced" accessories.
Rear Splash Guards $72.80
Running Boards $626.00
Wheel Locks $64.40
Total Accessories (Estimated) $763.20 **
** Prices shown are Acura suggested retail prices only. Labor is based on a $77/hr. rate multiplied by the national average installation time. Actual costs, labor rates and installation times may vary depending on region, market rate, etc. Dealers are free to set their own selling prices/labor rates. Prices shown do not include taxes or license. MSRP excludes tax, license, registration and options. Dealer prices may vary.
So, as you can see, yes, you (and rest of us) are getting ripped off. Like the previous post, you can negotiate but most of the dealers I tried to negotiate would simply would laugh and say, thats how much we charge and if you don't like em, take your business elsewhere....(see my posting on Dealer rating on Acura of Pleasanton).
Good Luck to you.
