Ok we all agree... Needs paint... Get out ths brush! Nerf covers might bring it to life as well!

I wanted to do white paint, I've just been so busy at work lately I haven't had much time to think about the car. White or black?

black or dark metallic purple

Well if they quoted you $3800 including painting the interior...as the itemized quote says (?) Then you can definitely complain and demand/expect them to paint it. If it's not in the quote, then really, it's nothing you should "expect".

As for the roll cage fabrication itself...the work looks solid, albeit not pretty.
