Mine is #178 and had the bubbles. The previous owner had the OEM hood repainted when new by the dealer under warranty (even though there wasn't a warranty). Fortunately the repaint went well and the hood is bubble-free.
#231 and it has bubbles. Was put off initially when I first viewed the car, but a little research put my mind at ease. One has to wonder if these cars ever reach ridiculous collector status, the original bubbled hoods will bring more dollars.
If nothing else, seeing the bubbles removes almost any doubt of the car's authenticity.
