What is the Build & Buy Car Buying Service? How subscribers can save money on a new car

Consumer Reports
This great service is provided by subscribers to Consumer Reports and can be accessed at most libraries on line with your library card. I used this service last time I purchased a car and it worked out well. The only problem I encountered was when I went to pay, the car dealer charged me an additional $100 because the "salesman made a mistake in addition."  The salesman could have made many more "mistakes" in the car dealer's favor if I had not used Consumer Reports.  Don't ever buy a car without checking what Consumer Reports says about its price and reliability. That goes for used as well as new cars.
