Alreet there, Some pillock decided to try and race me off the lights

in a fiat multipla full of his kids.
i didn't bite, and he trundled off and proceeded to not look in his mirrors, not realise that if i was not in front of him or behind him that i've not teleported to my destination.

And pulled into my lane and whacked the car on the mirror, front wing and bumper. and continued to drive off.

I overtook him and made him stop. Jumped out the car with my best angry face on. with a plan to be less than christian. (mrs is up the duff and he drove into us.) his explanation to this was "i thought i smoked you off the lights"

admitted liability. and wrote down his details as i was more concerned about the mrs and baby. gave them to us then left. After we'd had the mrs checked out. (ok luckily enough) i realised he didn't leave his insurance details just contact details.
So the mrs rung him and he was rude, saying he didn't cause any damage, like you obviously wouldn't driving into the side of someone at circa 30-40 mph. and that he wanted quotes in the post for the repair (fair enough) and photos of the damage (fair even though he looked at it.)
thing is the damage isn't that bad but, for the fact he was rude to the good lady on the phone about the price of the repair work (just under 300 quid) Should i be prepared to let him pay cash for the work, go through an accident management company or let our insurance sort it out?
also anyone reccomend a good body shop in bristol? anyone had work done by surecar? or any other ideas?
a kind one who might spray my valances at the same time would be nice
