[tamkingho200]

Basically, I have got a friend which have a T reg EVO 6, 23,000 UK CAR, he got an accident and crashed the front drive side. Its now under insurance to see if it could be fixed.

However I am sort of interested if its repair went ok and possibly buy it cheap. but my question us how cheap ? and what do i have to look at when i do inspection

Is it definatley going Cat D?
For value work out what it would be worth without being cat d and take ~20% off!
Might be more valueable as parts...
