Can I still put this car back onto my insurance? It is a car that was converted into a pickup truck

So I got bored one day and decided to make my 260,000 + mile 2001 Honda Civic into a truck by busting out the back windows and cutting out the roof, I drove it around that way to work, (police did not care at all, drove right past them) so later I put a piece of plywood to separate the cabin. And created custom headers to sound like a Subaru. Ended up selling it to a guy for $300, long story short he just texted me last night wanting me to buy it back, he needs the money for a speeding ticket from last year. Or so he says. He wanted $450, since he put in a passenger seat, and did some bodywork to make it more like a real truck. But anyway, my mom wouldn't let me buy it back from him, she says since we took it off insurance and turned in the plate, State Farm would have to look at the car before re-insuring. I told her this is not true, all you have to do is call to put it back on the policy. The guy I sold it to never put the title in his name, its still in ours. I know we will end up paying the property tax if he doesn't put it in his name, or someone else. I live in North Carolina. But, I want to know is my mom right or wrong about the car no longer being able to be insured due to such heavy modifications done to it? She hates the car, saying its ugly and very dangerous. She is scared if State Farm found out, they would raise her rates through the roof, she had them for 15 years. Here is the YouTube video of a quick walk around of the car.
