Well this is why jonny has asked them to come valuate the car and what its worth etc
he can the price the job accordingly
options for Dom are Write it off, get the payout, buy the car back super cheap and repair (jonny will sort him out a good price) and then pocket some cash
Downside is the car will be CAT D
OR
Price the job so it does not get written off, repair and dom is a happy chap but makes no money.. Car wont be CAT D tho
if this makes sense
either way its up to Dom, seems shame to CAT D this cat tho. jonny will sort you out whatever you decide
