State Attorney General Eric Schneiderman is suing some car dealerships in Queens for allegedly illegally inflating car prices.

Wednesday, Schneiderman's office announced the lawsuit, which claims that several Koeppel dealerships throughout Queens, owned by the Koeppel family, illegally sold "after-sale" services, such as identity theft protection and credit repair, to more than 1,400 customers.

As a result, customers were overcharged without their knowledge, according to the state attorney general's office.

The suit claims that between Jan. 2013 and Nov. 2014, the dealerships collected more than a million dollars through the practices, costing some costumers up to $2,000.

Schneiderman calls for the dealerships to refund affected customers.

Koeppel Auto Group said it is cooperating with the investigation.
