Would fixing cosmetic damage on my truck help it sell quicker?

I recently bought a 2006 Silverado for an absolute steal. I bought this truck with the intentions of flipping it for a small profit. It needed some fixing though.

So far I have about $500 invested in repairs to the truck. I put used tires on it with good tread, new headlights, new center console lid, an alignment, a fresh oil change, new rotors, new belt, and a new air filter. I also gave it a wash and wax and restored all the black trim, and the truck looks amazing.

However the only thing that needs replacing now is the rear bumper. Some kid backed into it, so the bumper is dented on the left corner, and it mashed the bed in a little behind it. The plastic step on top of the bumper also popped out and is sticking out a little.

Apart from that, the truck drives amazingly for being 10 years old and having 137,000 miles. I almost want to keep it for myself.

Anyways, I'm pretty much at my budget limit for fixing up the truck. Would fixing the bumper make it easier to sell the truck? It's about $150 for a new one. I'm going to ask the same price whether I fix it or not, I'm just asking if a buyer would be more interested if it was fixed??
