Karin
Karin is an automotive company in Grand Theft Auto IV. The company is likely based off the real-life manufacturer Toyota. However, the Sultan RS and Korean Mob Sultan, are modified like Subarus even though they are both based on a Lexus combined with a Mitsubishi; and the Intruder is based on Infinitis.
The name might be a parody of Kia as they spelled similarly and are girls' names; the logo also bears resemblance to their corporate logo (mainly the top left tip of the 'K').
