I dont know how bad your damage is but my personal experience was;
3 yrs back i argued with a van which buckled the front wing, broke the headlight unit & front bumper. write off ....i costed it then bought it back, part of letter i sent to insurer below;
I intend to put the vehicle back on the
road so I accept your offer for the perceived market value (£1350.00).
Please find enclosed Current MOT certificate V5C
registration certificate as
requested & return to me with a
cheque for; £912.50 (£1350-00 less the excess of £100-00 less the retention value of £337.50)
As the parts were only replacement work & respray, my son in law & I did the work & I also turned a profit of nearly £300, after paint/parts/mot etc..
at no time was i asked to re-register the car, only to re-MOT then inform DVLA.
If you intend to buy it back for rebuild, make sure you argue at least twice with the insurer about the buy back price. they will sometimes reduce the buy back cost & increase the percieved value if you argue (politely).
good luck whatever happens
