The amusing thing is, when I'd reversed into the bush (must've had a large branch poking out which was cut off), the rear bumper crunched so loudly my parents' first thought was that I was going to have to phone the insurance company and get the bumper replaced.
But the bark was certainly worse than the bite, the chip is no more than 1/2 a centimetre and there's a few scratches on the surface around the chip but it's not something that'll bother me in the long run.
What does bother me is how stupid I was for doing it in the first place, as I literally said to myself when I left the dealership that I would have to be careful when reversing the car, as there are no parking sensors.
Oh well, I'll leave it for a bit and if the chip genuinely bothers me that much, I'll get a dent/scratch repair person to come out and sort it. But until then, I'll live with it.
I could argue that now it's chipped, the rest of the paintwork will be protected from damage as I've got the necessary damage on it
