OKLAHOMA CITY (Reuters) – Car rental companies are offering discounts to Oklahoma residents looking to rent a vehicle, but some of them are selling the vehicles at far less than the advertised rates, a spokeswoman for the state Department of Motor Vehicles said on Thursday.

The state’s Office of Administrative Services said the department issued an alert last week asking car rental companies to provide their rates in Oklahoma on car rentals for the week ending July 20.

That includes a number of Oklahoma companies that advertise on their websites that they rent cars for $40 a day, but charge $40 for every additional day they stay in a vehicle that is not used, the agency said.

The company offering discounts was called Kia Motors Oklahoma and the vehicle was a 2003 Hyundai Sonata, according to the agency.

The vehicles can be rented for as little as $5 a day.

The prices vary depending on the rental company, according the agency, but a one-day rental for a 2004 Honda Civic can be $50.

On the Kia website, a company called KIEMO offers a $5 rate for one-way rentals for a vehicle with a 3,000-mile (5,000 kilometer) range and a fuel economy rating of 25 miles per gallon.

The rate is $20 for the day and $30 for the month, according a listing on the company’s website.

The listing says a one month rental costs $55, and the rental lasts for a total of 12 days.

A month rental for the Honda Civic costs $85.KIEME said its vehicles can rent for as low as $20 a day for a three-day trip or for as high as $75 for a 12-day stay.

The company said it does not rent its vehicles to individuals who have been convicted of drug or alcohol-related offenses.

The Oklahoma state attorney general’s office said in a statement that it is investigating the KIERO.

A spokeswoman for KIOMO, Tanya Tarkanian, said in an email on Thursday that the company is cooperating with the investigation.

“The company’s policies and practices require that its vehicles are available for rental, even when they are not used.

However, KIORE does not provide its vehicles with any warranty, and it will not return any vehicles that are not available for use,” Tarkani said.

In Oklahoma, a driver’s license is required to drive a vehicle.
