Car dealers reigned at the top of the consumer gripe list for 2010, the second year in a row they held that distinction, according to the Better Business Bureau of Minnesota and North Dakota.

The local BBB chapter took 24,491 complaints last year regarding businesses, about 1,000 fewer from 2009. Here are the most common categories:

1.New car dealers
2.Used car dealers
3.Siding contractors

5.Contractors – general
6.Roofing contractors
7.Construction & remodeling services
8.Banks
9.Window installation & services
10.Cable and satellite TV
