It needs 2 new intercoolers, set of headlights, front bumper + some bodywork. Are the repairs something that an amateur - with a proper manual and/or guidance - could do?
Forgot to add: it's a UK car.

I think yes,don't know the cost

My son is an Audi technician and he tells me constantly about how much more damage people do to Audi's that try to repair them that don't know what they are doing so I would say to take it to a professional Audi technician to save money in the long run. Remember these wise words!
