I've lived my whole life unable to buy a car or an oil change on Sundays. Have you ever wondered why you can't service or buy a car on Sundays here in Minnesota? I'm not saying that we need to buy cars on Sundays, but there are only 13 states left in the US that don't offer car sales on Sundays.

Minnesota law states that selling a car on Sundays is a misdemeanor. Check it out:

Minnesota Statute 168.275

Any person who shall carry on or engage in the business of buying, selling, exchanging, dealing in or trading in new or used motor vehicles; or who shall open any place of business or lot wherein the person attempts to or does engage in the business of buying, selling, exchanging, dealing or trading in new or used motor vehicles; or who does buy, sell, exchange, deal or trade in new or used motor vehicles as a business on the first day of the week, commonly known and designated as Sunday, is guilty of a misdemeanor for the first offense, and a gross misdemeanor for each succeeding offense.

According to Finn.com the 13 states, which includes Minnesota that don't allow car sales on a Sunday are:

Colorado
Indiana
Illinois
Iowa
Louisiana
Maine
Minnesota
Mississippi
Missouri
New Jersey
Oklahoma
Pennsylvania
Wisconsin

Other states that restrict the hours or sales permitted in certain counties include:

Maryland
Michigan
Nevada
North Carolina
Rhode Island
Texas
Utah

But why is this a law? Well, the Minnesota Automobile Dealer Association supports the ban on Sunday sales, as they believe it wouldn't help to sell more cars but increase the overhead on dealerships.

Dealerships will sell no more cars in a year but will increase overhead by adding another day to their operating week -- it will increase dealers’ costs by approximately $20 million annually - MADA

So until the people working in the industry want to be open on Sundays it doesn't appear we can buy a car on Sunday.
