The Lowrider DLC for GTA Online is out today and it contains various customization options for your vehicle. Some are rather flashy. Others are quite hideous, which more or less boils down to subjective interests and perspectives, really.
Customization in the DLC is available for six cars, two of which are new with the DLC. It's not just hydraulics and a crazy exterior either. According to Arekkz Gaming, there are various options available for the interior as well.
Another video featuring customization applied to all six cars is posted below.
Along with the Lowrider vehicles, the content also includes 200 weapons for Freemode, some taunts, a single-player gun and quite a bit more.
