Unfortunately had a bump today

and with 300K on the clock I`m sure the insurance will write it off if I go down that route. I don`t expect it will be worth much so if I make a claim or not I have the following options.
52 reg Olympus Dti Star Silver, 60000miles, 5 speed, on 2nd engine, still runs great, no issues or EML`s
Damage is the following,
Front Bullbar
Front plastic bumper
Front Grill
OSF Headlight broken mounting
Front radiator support bent
Bonnet
Radiator
Air Con Rad
Bent intercooler ( Turbo still boosts )
Still drives and managed to drive back to our yard, no crunching or grinding noises.
So all cosmetic so could be easily put back togather, which I could do myself.
Regarding the accident ( My fault )

nodody was injured which is the best news

. Short of it, followed a train of cars through a traffic light ( Green ) for them all to suddenly stop, and right where I had to emergency brake there is a water leak (spring) in the road, which ended up in me locking up and sliding into the car in front. No time for the ABS to kick in. The transit tipper that caused everyone to brake was just dropping off a passenger. Unfortunately there were no other alternatives with pedrestrians, on the side walk and oncoming traffic in the opposite lane, so just had to stay straight. No airbags deployed.
The options,
1, Pay the excess ( £250.00 ) scrap the vehicle, take what im offered look for something new. Least prefered option.
2 Pay the excess buy it back and fix it myself , with a future title on it, although may have something to put towards the parts for repairs.
3, Notify insures, don`t make a claim and fix myself. All my cost.
At the moment I have notified my insures and have taken the time to ponder my options.
Any Suggestions. I have the use of other vehicles so does not have to be an immediate fix. The down side is I unable to tow my track car around or collect parts for my other toys.
