Hiya Mike,
I havent had a reason for the respray buddy - the car is HPi clear etc, so no issue with damage.
I would assume the car has been in need of a tidy up - paint scratches, maybe some corner scuffs from use, so in this guys eyes a tidy up is a respray.
Its not the cheapest of sprays as you know, so think he just wanted to make it as mint as possible after almost 60K miles of usage (around the mileage it got the spray job).
Its came to me through a trade contact - totally in two minds to sell, but hoping a sensible winter offer comes along!
