However, that doesn't mean you won't run into any problems or that you won't get ripped off. It's still common to find "errors" in paperwork or problems with a new car after you've driven off the lot.
In most cases, dealers will try to rectify the situation when you contact them, but there's always a few that require a heavier hand to get things settled. If you encounter a problem, your first line of defense is to use the Customer Satisfaction Survey as a negotiation tool.
The CSS is a survey that is sent by the manufacturer to each new car buyer in order to get feedback on the dealership. They usually arrive via mail after a few weeks. Unlike many other product surveys, this is actually very important to dealers. Manufacturers use these surveys to determine how many cars to allocate to dealers, and to determine bonus amounts that will be paid.
If a dealer consistently gets high marks on these surveys, they will usually get large bonus payments and first dibs on the hottest selling cars on the market. The way to use the CSS is to call the general manager or sales manager at the dealership. Let them know you're not happy with the situation and that you will be filling out the CSS soon. Tell them you will be happy to give them high marks if the problem is fixed.
This will usually do the trick if it's a small issue, but sometimes dealers are very hard-headed and you have to take it to the next level.
One thing dealers fear most are customers who file complaints with the State Attorney General. If a dealer gets too many complaints, they could be fined or even have their franchise license revoked, so they take these very seriously.
Let them know that you will be filing a complaint with the State Attorney General and also the Better Business Bureau. That will certainly get their attention. You can take it even further by threatening to leave bad ratings on several dealer review web sites. Most dealers feel it's very important to have a good online reputation, so they will want to prevent bad reviews online.
If none of this works and the problem is serious enough, you can hire a lawyer or try to contact your local news to see if they will do a story. Hopefully, you won't need to resort to this - and in most cases you shouldn't have to if the dealer is smart.
