DVLA have already issued a log book and taxed for road use so its only a case of has the work been done properly (looks so from the pictures) and whats it worth. A good friend in the motor trade tells me that as a rule of thumb: a satisfactorily repaired Cat C should cost no more than 50% of the market value of a straight car. I would expect to pay less than that for a Cat B but then this is a rare Aeromax.
