Unless someone has time to analyze the parts catalog for dash panel costs compared to the Volts and say the Impala, it's pure speculation that the interior is "cheap"...The Volt and even the Vette's base has "hard plastics" on the dash, yet the Vette has trims/options that adds leather/suede inserts to partially cover the dash...
The elephant in the room is the white/cream lower dash, that to many, is what people think makes it look "cheap"...If you're handy, could remove the upper dash, lower dash and white door panels and have an upholsterer add a nice material to it...Furthermore, simply spraying a coat of plastidip on them (be sure to remove them from the car) can add a textured upscale look...It's like $5/can, you can easily remove it if you don't like it...Fun way to kill a couple of hours...
